Floating-Harbor syndrome (FHS) is a rare autosomal dominant genetic disorder characterized by proportionately short stature, lack of expressive language, and distinctive facial features, including a large nose, long eyelashes, deeply set eyes, and a triangular face. We present a case of an 11-year-old Korean girl who was initially suspected of having Noonan-like syndrome but was later diagnosed with Floating-Harbor syndrome. The patient exhibited short stature, developmental language delay, dysmorphic facial features, and early puberty...

Schwartz-Jampel Syndrome (SJS) type-1 (OMIM; #255800), a rare cause of skeletal dysplasia, is characterized by myotonic myopathy, chondrodystrophy, short stature, facial and eye abnormalities. SJS Type-1 develops due to variations in the HSPG2 gene which produces the "perlecan" molecule, one of the main proteoglycans of the basement membrane. A 6-year-old girl presented with short stature, a mask face, shrunken lips, narrow palpebral opening due to blepharospasm, stiffness of facial muscles, micrognathia, overlapping teeth, a short neck, and a bell-shaped thorax due to myotonic myopathy...

46, XX individuals born with severely masculinized genitals due to congenital adrenal hyperplasia (CAH) who have been assigned males at birth and reared male can successfully establish a male gender identity/role, find employment, marry, function sexually with a female partner, and develop positive mental health status. While there were a few individuals who reportedly did not fare well or who changed gender to female, the majority of those identifying as males appear to have an overall good quality of life...

OBJECTIVE: Prader-Willi Syndrome (PWS) and Bardet-Biedl syndrome (BBS) are common cause of pediatric syndromic obesity. We aim to investigate a possible role of ghrelin and glukagon-like peptid-1 (GLP-1) in pathophysiology of Prader-Willi Syndrome (PWS) and Bardet-Biedl syndrome (BBS). METHODS: We recruited 12 subjects with PWS, 12 subjects with BBS, 13 obese controls (OC) and 12 lean controls (LC). Fasting serum ghrelin and GLP-1 levels were measured by ELISA method...

In terms of prevalence, 11β-hydroxylase deficiency (11β-OHD), a common form of congenital adrenal hyperplasia, closely follows 21-hydroxylase deficiency. 11β-OHD has been attributed to diminished enzymatic activity owing to CYP11B1 gene variants, mainly encompassing single nucleotide variations and insertions-deletions. The involvement of chimeric CYP11B2/CYP11B1 genes in 11β-OHD has been rarely reported. We conducted a genetic investigation on a male infant with generalized pigmentation and abnormal steroid hormone levels...

3'-Phosphoadenosine 5'-phosphosulfate synthase 2 (PAPSS2) deficiency is a rare disorder due to biallelic pathogenic variants in the PAPSS2 gene. This disorder was first described in 1998 by Ahmad M, et al. and Faiyaz ul Haque M et al .. So far 79 patients with PAPSS2 deficiency were reported in the literature. The main reported features of these patients are related to bone abnormalities and clinical/biochemical androgen excess. Disproportionate short stature and symptoms associated with spondylar skeletal dysplasia are the most common clinical features that require clinical attention...

Primary pigmented nodular adrenocortical disease (PPNAD) is a rare genetic disease mainly associated with Carney complex (CNC), which is caused by germline mutations of the regulatory subunit type 1A (RIα) of the cAMP-dependent protein kinase (PRKAR1A) gene. We report three cases suffering from CNC with unique features in diagnosis and follow-up. All cases had obesity and a cushingoid appearance and exhibited laboratory characteristics of hypercortisolism. However biochemical and radiological examinations initially suggested Cushing's disease in one case ...

Autoimmune polyendocrine syndrome type 1 (APS-1), also referred to as autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), is a rare monogenic autosomal recessive autoimmune disease. It is caused by mutations in the autoimmune regulator ( AIRE ) gene. APS-1 is diagnosed clinically by the presence of two of the three major components: chronic mucocutaneous candidiasis (CMC), hypoparathyroidism, and primary adrenocortical insufficiency. A 3.3-year-old girl was presented with a carpopedal spasm to the pediatric emergency clinic...

OBJECTIVE: Maturity-onset diabetes of the young (MODY) is the most common type of monogenic diabetes. To date, mutations have been identified in 14 different genes of patients with a clinical diagnosis of MODY. This study screened mutations in 14 MODY-related genes and the regulator factor X6 (RFX6) gene in children. MATERIALS AND METHODS: The presence of clinical features of MODY and negative results for three autoantibody markers of T1DM in children and adolescents were used as inclusion criteria for genetic testing...

Congenital hypothyroidism (CH), if not correctly treated with L-thyroxine (L-T4), may be responsible for a permanent intellectual disability. If patients treated with L-T4 do not achieve a good TSH control, the possibility of poor compliance and/or poor absorption of L- T4 should be investigated. We describe an infant with CH whose thyroid hormone levels worsened after she started a carob-bean gum thickened formula. A baby girl was diagnosed with CH by newborn screening (at confirmatory blood evaluation TSH was 496...

OBJECTIVE: To compare pulse wave analysis (PWA) of obese children with and without metabolic syndrome (MS) with healthy, non-obese children and to evaluate the association between PWA findings and additional risk factors present in children with MS and obesity. METHODS: From the obese patients examined between June 2019 and June 2021, 41 patients with MS, 36 obese patients without MS, and 34 healthy non-obese children of similar age and gender were evaluated retrospectively...

Neonatal diabetes and congenital hypothyroidism (CH) syndrome is a rare condition caused by homozygous or compound heterozygous mutations in the GLIS3 gene. Small for gestational age, congenital glaucoma, polycystic kidney disease, cholestatic hepatic fibrosis, pancreatic exocrine insufficiency, developmental delay, dysmorphic facial features, sensorineural deafness, osteopenia, and skeletal anomalies are other accompanying phenotypic features in the 22 cases described so far. We present a male patient with neonatal diabetes, CH, congenital glaucoma, developmental delay, and facial dysmorphism...

Here we report an adolescent boy diagnosed with ectopic ACTH (Adrenocorticotropin hormone) syndrome (EAS) caused by atypical bronchial carcinoid. The patient was evaluated multidisciplinaryly: he had surgery and took chemotherapy and radiotherapy treatments afterward. The patient is still under our follow-up. Until today eighteen pediatric and adolescent patients with EAS because of bronchial carcinoid tumors were reported in 13 case reports and literature reviews. Ectopic ACTH syndrome caused by bronchial carcinoids is very rare in children and adolescents...

Hereditary forms of Medullary thyroid carcinoma (MTC) are rare. Different phenotypes with the same mutation may be due to differences in the timing of RET activation steps, additional mutations in other regions of the gene, or the co-occurrence of germline and somatic mutations, which is an infrequent possibility. Here, we aim to present the different features and difficulties in the follow-up of three family members with the same germline mutation. A 4-year-old male patient with respiratory distress was diagnosed with MTC and found to have a heterozygous germline mutation C...

OBJECTIVE: Ischemia-modified albumin (IMA) formation is associated with increased reactive oxygen species (ROS) production, while cortisol leads to decreased ROS levels. We aimed to evaluate the effect of ACTH stimulation on IMA levels and whether the effect is dose-dependent or not. METHODS: A total of 99 subjects with normal ACTH test results were included in the study, where 80 subjects were performed to standard-dose ACTH test while 19 subjects were performed to low-dose ACTH test...

Adenylate cyclase 3 (ADCY3) gene alterations have been found to be associated with obesity. However, few patients with homozygous mutations have been reported so far, and the follow-up procedure and treatment options have not been clarified. A 10-month-old female presented with increased appetite and weight gain. She was born from a consanguineous marriage. Weight, height, head circumference measurements and standard deviation scores (SDS) were 19 kg (+6.98 SDS), 82 cm (+3.53 SDS), and 49 cm (+3.07 SDS), respectively...

OBJECTIVE: Children born small for gestational age (SGA) are at a greater risk of developing insulin resistance, type 2 diabetes, and cardiovascular disease in adulthood. Gastrointestinal peptides regulate glucose and lipid metabolism and act on the hypothalamus to regulate energy homeostasis. This study aimed to explore whether gastrointestinal peptides are involved in metabolic disorders in SGA, which remains unclear. METHODS: We detected the secretion of glucagon-like peptide 1 (GLP-1) and peptide YY (PYY) in prepubertal children born SGA, compared the differences between catch-up growth and persistent short stature, and analyzed their correlations with glucose and lipid metabolism...

OBJECTIVE: Noonan syndrome (NS) is characterized by dysmorphic facial features, short stature, congenital heart defects, and varying levels of developmental delays. It is a genetic, multisystem disorder with autosomal dominant inheritance and is the most common of the RASopathies. In approximately 50% of patients, NS is caused by variants in the Protein Tyrosine Phosphatase Non-Receptor Type 11 ( PTPN11 ). This study aimed to evaluate two patients with the previously reported PTPN11 variant in a homozygous state for the first time and seven other family members carrying the same heterozygous variant in terms of clinical, biochemical, genetic, and response to treatment...
