OR11-002 - Mutations in MVK cause non-syndromic RP
نویسندگان
چکیده
Methods After detailed clinical characterization including funduscopy and optic coherence tomography, exome sequencing analysis was performed in a proband of Dutch origin with non-syndromic autosomal recessive RP. Identified mutations were tested for segregation within the family and in a large cohort of genetically unsolved RP patients. Upon identification of mutations in MVK, encoding mevalonate kinase (MK), patients with mutations in this gene underwent extensive clinical re-examination. MK enzyme activity was analyzed in cultured lymphoblastoid cells and mevalonic acid levels were measured in urine samples.

Relative frequency of GJB2 gene mutations in autosomal recessive non-syndromic hearing loss (ARNSHL) patients in Lorestan population
Background: Congenital hearing loss due to different genetic and environmental causes affects 1 in 1000 newborns. Mutations in the GJB2 (Gap Junction Beta-2) gene encoding the gap junction protein connexin 26 have been established as the main cause of autosomal recessive non-syndromic hearing loss. Materials and methods: The aim of this study was to study the frequency of GJB2 Mutations in Lor...

Abstract Background and aim: The frequency of hearing impairment is one out of 500 newborn babies, worldwide. However, in Iran, due to the high prevalence of consanguineous marriages, this amount is estimated to be two to three times higher. So far, more than 120 genes causing non-syndromic Hearing loss (NSHL) have been identified in the world, of which GJB2 gene mutations are the most common c...
متن کاملSyndromic and non-syndromic forms of retinitis pigmentosa: a comprehensive Italian clinical and molecular study reveals new mutations.
Mutations in more than 60 different genes have been associated with non-syndromic and syndromic retinitis pigmentosa (RP), a heterogeneous group of inherited retinal dystrophies. To increase the understanding of the molecular epidemiology of the disease in Italy, we analyzed 56 patients with syndromic and non-syndromic forms of RP attending the Retinitis Pigmentosa Center of San Paolo Hospital ...
متن کاملInvestigation of LRTOMT gene (locus DFNB63) mutations in Iranian patients with autosomal recessive non-syndromic hearing loss
Hearing loss (HL) is the most frequent sensory defect affecting 1 in 1000 neonates. This can occur due to genetic or environmental causes or both. The genetic causes are very heterogenous and over 100 loci have been identified to cause autosomal recessive non - syndromic hearing loss (ARNSHL). The aim of this study was to determine the contribution of the LRTOMT gene mutations in causing ARNSHL...
متن کاملDiagnostic Challenges in Retinitis Pigmentosa: Genotypic Multiplicity and Phenotypic Variability
Retinitis pigmentosa (RP) is a heterogeneous group of inherited retinal disorders. Diagnosis can be challenging as more than 40 genes are known to cause non-syndromic RP and phenotypic expression can differ significantly resulting in variations in disease severity, age of onset, rate of progression, and clinical findings. We describe the clinical manifestations of RP, the more commonly known ca...
