Three Novel Mutations in Iranian Patients with Tay-Sachs Disease
Background: Tay-Sachs disease (TSD), or GM2 gangliosidosis, is a lethal autosomal recessive neurodegenerative disorder, which is caused by a deficiency of beta-hexosaminidase A (HEXA), resulting in lysosomal accumulation of GM2 ganglioside. The aim of this study was to identify the TSD-causing mutations in an Iranian population. Methods: In this study, we examined 31 patients for TSD-causing m...
متن کاملIdentification of Three Novel Mutations in the FRMD7 Gene for X-linked Idiopathic Congenital Nystagmus
Idiopathic congenital nystagmus (ICN) consists of involuntary and periodic ocular motility, often with seriously reduced visual acuity. To identify the genetic defects associated with X-linked ICN, we performed PCR-based DNA direct sequencing of two candidate genes, FRMD7 and GPR143, in four families. Mutation analysis led to identification of three novel mutations, p.S260R, p.Q487X, and p.V549...
متن کاملNystagmus in Enlarged Vestibular Aqueduct: A Case Series
Enlarged vestibular aqueduct (EVA) is one of the commonly identified congenital temporal bone abnormalities associated with sensorineural hearing loss. Hearing loss may be unilateral or bilateral, and typically presents at birth or in early childhood. Vestibular symptoms have been reported in up to 50% of affected individuals, and may be delayed in onset until adulthood. The details of nystagmu...

background: tay-sachs disease (tsd), or gm2 gangliosidosis, is a lethal autosomal recessive neurodegenerative disorder, which is caused by a deficiency of beta-hexosaminidase a (hexa), resulting in lysosomal accumulation of gm2 ganglioside. the aim of this study was to identify the tsd-causing mutations in an iranian population. methods: in this study, we examined 31 patients for tsd-causing mu...
متن کاملIdentification and functional analysis of two novel connexin 50 mutations associated with autosome dominant congenital cataracts
Autosomal dominant congenital cataracts (ADCC) are clinically and genetically heterogeneous diseases. The present study recruited two Chinese families with bilateral nuclear cataract or zonular pulverulent phenotype. Direct sequencing of candidate genes identified two novel missense mutations of Cx50, Cx50P59A (c.175C > G) and Cx50R76H (c.227G > A), both co-segregated well with all affected ind...
