Empty follicle syndrome (EFS) is a disorder associated with female infertility and presents as a complete failure to retrieve oocytes during ART cycles despite normal follicle development and careful aspiration. To date, only two EFS cases have been reported with homozygous missense mutations in the luteinizing hormone/chorionic gonadotropin receptor (LHCGR) gene, and both cases showed normal estradiol (E2) production during ovulation induction. The molecular genetic mechanisms of EFS remain unknown. Herein, we report two novel homozygous inactivating LHCGR mutations, c...

PURPOSE OF REVIEW: To summarize the current advances in our understanding or the genetic basis of nonbacterial osteomyelitis. RECENT FINDINGS: Chronic recurrent multifocal osteomyelitis (CRMO) is a complex genetic disorder. Past discoveries identified several single gene defects (LPIN2, Pstpip2 and IL1RN) that cause IL-1-mediated sterile multifocal osteomyelitis. Recently Lorden et al.'s studies show that LIPIN2 deficiency can activate the NLRP3 inflammasome through alterations in the function of P2X7 receptor providing evidence that Majeed syndrome is an NLRP3 inflammasomopathy...

Irish Travellers are an endogamous nomadic ethnic minority population mostly resident on the island of Ireland with smaller populations living in Europe & USA. As they practice consanguinity, rare and ultra-rare autosomal recessive conditions are observed which are infrequently seen in the general population. Awareness of the rare genetic disorders within an antenatal setting that recur within this population should facilitate quicker cost-effective diagnosis. These include disorders leading to recurrent miscarriage and multiple congenital anomalies...

Signal transducer and activator of transcription 3 (STAT3) is a central regulator of immune homeostasis. STAT3 levels are strictly controlled, and STAT3 impairment contributes to several diseases including the monogenic autosomal-dominant hyper-immunoglobulin E (IgE) syndrome (AD-HIES). We investigated patients of four consanguineous families with an autosomal-recessive disorder resembling the phenotype of AD-HIES, with symptoms of immunodeficiency, recurrent infections, skeletal abnormalities, and elevated IgE...

Mucolipidoses are metabolic disorders with autosomal recessive inheritance caused by deficiency of N-acetylglucosamine- 1-phosphotransferase leading to accumulation of glycosaminoglycans and sphingolipids intracellularly. The differential diagnosis of mucolipidosis II or III is based on the age of onset, clinical findings and degree of severity. In this article, we present four pediatric patients with mucolipidosis III or pseudo-Hurler polydystrophy who admitted to our hospital with joint stiffness. They were from consanguineous families with characteristic radiographic findings...

Retinitis pigmentosa (RP) is the most frequent genetically and clinically heterogeneous inherited retinal degeneration. To date, more than 80 genes have been identified that cause autosomal dominant, autosomal recessive and X linked RP. However, locus and allelic heterogeneity of RP has not been fully captured yet. This heterogeneity and lack of an accurate genotype phenotype correlation makes molecular dissection of the disease more difficult. The present study was designed to characterize the underlying pathogenic variants of RP in Pakistan...

MYF5 is member of the Myc-like basic helix-loop-helix transcription factor family and, in cooperation with other myogenic regulatory factors MYOD and MYF5, is a key regulator of early stages of myogenesis. Here, we report three consanguineous families with biallelic homozygous loss-of-function mutations in MYF5 who define a clinical disorder characterized by congenital ophthalmoplegia with scoliosis and vertebral and rib anomalies. The clinical phenotype overlaps strikingly with that reported in several Myf5 knockout mouse models...

SECISBP2 is an essential factor in selenoprotein synthesis and its mutations result in a multiorgan syndrome including abnormal thyroid hormone metabolism. A ten-year-old obese Turkish boy born to consanguineous parents presented with high T4, low T3, high rT3 and normal or slightly elevated TSH. He also had attention deficit disorder and muscle weakness but no delay in growth or bone age. Sequencing of genomic DNA revealed a novel c.800_801insA, p.K267Kfs*2 mutation, homozygous in the proband and heterozygous in both parents and his brother...

Various genetic defects can cause intellectual and developmental disabilities (IDD). Often IDD is a symptom of a more complex neurodevelopmental or neurodegenerative syndrome. Identifying syndromic patterns is substantive for diagnostics and for understanding the pathomechanism of a disease. Recessive GPT2 mutations have recently been associated with IDD in four families. Here, we report a novel recessive GPT2 stop mutation p.Gln24* causing a complex IDD phenotype in a homozygous state in five patients from two consanguineous Arab families...
