ambiguous genitalia

KEY CLINICAL MESSAGE: Jacobs syndrome and congenital adrenal hyperplasia are separate entities but share common clinical features such as ambiguous genitalia. Further studies are needed to conclude the relationship between Jacobs syndrome and congenital adrenal hyperplasia. ABSTRACT: A 5-month-old male infant was evaluated for ambiguous genitalia. Examination revealed cryptorchidism, inguinal hernia, long phallus, and Grade 3 scrotal hypospadias. Serum 17-OH progesterone was high and chromosomal analysis showed 47XYY/45XO...

Alterations in gonad formation or function can lead to congenital conditions in which chromosomal, gonadal, or anatomical sex is atypical. These conditions are referred to as disorders of sex development (DSD) and have a heterogeneous etiology. The assessment of these children by a multidisciplinary team is crucial for an accurate diagnosis and should be initiated promptly due to the potentially life-threatening nature of congenital adrenal hyperplasia, a common cause of DSD. We present a neonate born at 39 weeks with a weak cry, slight hypotonia, poor suction reflex, peculiar facies, and ambiguous genitalia...

Bladder agenesis is a rare congenital deformity characterized by the absence of the bladder. It is primarily observed in postmortem dissections of stillbirths rather than live births. The condition is often associated with other congenital anomalies, leading to the hypothesis that most affected fetuses do not survive to term. However, the exact cause and specific associated anomalies remain unclear and poorly described in the literature. The limited mention of bladder agenesis in textbooks and literature underscores the importance of creating a comprehensive source for future research in this field...

Differences of sexual development (DSD) refers to congenital conditions characterized by discordant appearances of external genitalia with respect to sex chromosomes. We present a case of a 46 XY DSD adolescent with bilateral undescended testes and severe scrotolabial anomalies who was lost to follow-up for several years who recently presented with "recurrent UTIs." Although the patient desired immediate reconstruction to void while standing, shared-decision making was used to first address his bilateral cryptorchidism, with plans to delay other reconstruction until the patient is older...

OBJECTIVE: The aim of this study was to review the prenatal findings of disorders of sex development (DSD) cases postnatally diagnosed in our tertiary referral center. METHODS: We evaluated 57 DSD cases with sex ambiguity who had undergone prenatal ultrasound with phenotypic sex assessment and/or cell-free fetal DNA (cffDNA) for genotypic sex assessment. RESULTS: Prenatal cffDNA had been performed in 32, being positive (suggestive of male genotypic sex) in 26 and negative (suggestive of female genotypic sex) in six...

Although 17β-hydroxysteroid dehydrogenase type 3 (HSD17B3) deficiency is diagnosed when a testosterone/androstenedione (T/A-dione) ratio after human chorionic gonadotropin (hCG) stimulation is below 0.8, this cut-off value is primarily based on hormonal data measured by conventional immunoassay (IA) in patients with feminized or ambiguous genitalia. We examined two 46,XY Japanese patients with undermasculinized genitalia including hypospadias (patient 1 and patient 2). Endocrine studies by IA showed well increased serum T value after hCG stimulation (2...

Differences of sex development (DSDs) are a spectrum of congenital clinical conditions involving the development of gonadal, chromosomal, and anatomical sex. The physical presentation provides incomplete clues because underlying etiologies may present with similar findings. We describe an 8-year-old boy from the Dominican Republic originally diagnosed with congenital adrenal hyperplasia (CAH). He was prescribed oral hydrocortisone and fludrocortisone, with irregular adherence. During infancy, he had human chorionic gonadotropin injections to stimulate phallic growth...

During development, the deletion of DNA from chromosome 13's short arm (q) causes a chromosomal abnormality known as chromosome 13q deletion syndrome. Chromosome 13 terminal deletions are rare and may cause various congenital disabilities, and only a few cases have been reported in the literature. The extent of chromosome 13q deletion syndrome changes lacks consistent clinical features, with no recorded cases of genital ambiguity until now. We report the case of a newborn male patient whose testes had descended on both sides; he had ambiguous genitalia, and the dorsal surface of his penis was attached to his scrotal sac...

Cytochrome P450 oxidoreductase deficiency (PORD) is a rare form of congenital adrenal hyperplasia that can manifest with skeletal malformations, ambiguous genitalia, and menstrual disorders caused by cytochrome P450 oxidoreductase (POR) mutations affecting electron transfer to all microsomal cytochrome P450 and some non-P450 enzymes involved in cholesterol, sterol, and drug metabolism. With the advancement of molecular biology and medical genetics, increasing numbers of PORD cases were reported, and the clinical spectrum of PORD was extended with studies on underlying mechanisms of phenotype-genotype correlations and optimum treatment...

Noninvasive prenatal testing (NIPT) is commonly used to screen for fetal trisomy 13, 18, and 21 and often for sex chromosomal aneuploidies (SCAs). Although the testing is also used for sex chromosomal aneuploidies, it is not as efficient as it is for common trisomies. In this particular study, we present a case for whom the NIPT diagnosis was originally 45,X and who was diagnosed with mixed gonadal dysgenesis 45,X/46,XY after birth. A 38-year-old [G3P3] pregnant woman underwent NIPT at 15 weeks' gestation and was found to be at probable risk for 45,X...

Copy number variants that duplicate distal upstream enhancer elements of the SOX9 gene cause 46,XX testicular differences of sex development (DSD) which is characterized by a 46,XX karyotype in an individual presenting with either ambiguous genitalia or genitalia with varying degrees of virilization, including those resembling typical male genitalia. Reported duplications in this region range in size from 24 to 780 kilobases (kb). Here we report a family with two affected individuals, the proband and his maternal uncle, harboring a 3...

In patients with 46,XY disorders of sex development (DSDs), next-generation sequencing (NGS) has high diagnostic efficiency. One contribution to this diagnostic approach is the possibility of applying reverse phenotyping when a variant in a gene associated with multiple organ hits is found. Our aim is to report a case of a patient with 46,XY DSDs in whom the identification of a novel variant in MYRF led to the detection of a clinically inapparent congenital heart defect. A full-term newborn presented with ambiguous genitalia, as follows: a 2 cm phallus, penoscrotal hypospadias, partially fused labioscrotal folds, an anogenital distance of 1...

Ambiguous genitalia is a matter of concern and needs thorough evaluation and treatment. Gonadectomy becomes a potentially lifesaving procedure in patients with partial androgen insensitivity due to the increased risk of malignancy if left undiagnosed. We present a case report of two patients in their late 20s and 30s, raised as girls, who came with complaints of primary amenorrhea with ambiguous genitalia. Both patients had features of masculinization. Her MRI revealed an absent uterus, cervix, upper 2/3 of the vagina, and ovaries, with the presence of bilateral testicles...

Lethal multiple pterygium syndrome is a very rare genetic disorder. The manifestations of this condition include growth deficiency of the fetus, craniofacial anomalies, joint contracture, and skin webbing (pterygia). This disorder is fatal before birth or shortly after birth. We reported a case of lethal multiple pterygium syndrome with multiple anomalies including pterygia involving the axilla, bilateral antecubital fossa, and groin. Arthrogryposis involving multiple lower and upper extremities joints. Cleft palate, microstomia and limitation of mouth opening, webbed neck, asymmetric small and narrow chest, ambiguous genitalia, depressed and wide nasal bridge, antemongoloid slant, low-set, malformed, and posteriorly rotated ears, pterygia, syndactyly and camptodactyly of hands and rocket bottom feet...

NR5A1/SF-1 (Steroidogenic factor-1) variants may cause mild to severe differences of sex development (DSD) or may be found in healthy carriers. The NR5A1/SF-1 c.437G>C/p.Gly146Ala variant is common in individuals with a DSD and has been suggested to act as a susceptibility factor for adrenal disease or cryptorchidism. Since the allele frequency is high in the general population, and the functional testing of the p.Gly146Ala variant revealed inconclusive results, the disease-causing effect of this variant has been questioned...

A case is reported herein of a true hermaphrodite (TH) with an ovotestis, a uterus, a vagina, and an underdeveloped phallus. The patient was raised by his parents as a male, based on the presence of a phallus with ambiguous genitalia. He started experiencing breast enlargement at the age of 14 and menarche by the age of 17. He was reviewed using ultrasound, magnetic resonance imaging of the abdomen, and karyotyping, and the reports showed evidence of Mullerian structures and 46 XX karyotyping. Based on the preferences of the patient and his parents and their psychological outlook toward the male gender, a total mastectomy, hysterectomy, bilateral gonadectomy, and total vaginectomy were performed...

OBJECTIVES: To generate gestation-wise normative data of external genitalia measurements in North Indian term and preterm male newborns. METHODS: This was a hospital-based cross-sectional observational study. Male neonates born between 28-42 wk of gestation (at 24-72 h of life) were consecutively recruited in the study. Newborns with major congenital malformations, chromosomal anomalies, multifetal gestation and birth injuries were excluded. Data on various genital measurements were collected [Stretched penile length (SPL), penile width (PW), upper anogenital distance (AGDu), lower anogenital distance (AGDl) and anogenital ratio (AGR)]...

BACKGROUND: Congenital Adrenal Hyperplasia (CAH) is a chronic disease that requires lifelong treatment. Patients may face stigmatization, which may affect their quality of life (QoL). Therefore, we assessed the clinical characteristics and QoL of patients with CAH in the Middle East. METHODS: This case-control study included patients with CAH aged >5 years from two tertiary centers (2020-2021). The patients were matched to a healthy control group and were then divided into pediatric and adult groups...

The aim of the study was to analyze the clinical suspicion and where patients were when they received the positive result of the neonatal screening for CAH 21OHD. The present data derived from a retrospective analysis of a relatively large group of patients with classical CAH 21OHD patients nosed by newborn screening in Madrid, Spain. During the period from 1990 to 2015 of this study 46 children were diagnosed with classical 21OHD [36 with the salt-wasting (SW) form and 10 with simple virilizing (SV)]. In 38 patients, the disease had not been suspected before the neonatal screening result (30 SW and 8 SV)...
