Spectrum of GJB2 (Cx26) gene mutations in Iranian Azeri patients with nonsyndromic autosomal recessive hearing loss.
OBJECTIVE Hereditary hearing impairment is a genetically heterogeneous disorder. In spite of this, mutations in the GJB2 gene, encoding connexin 26 (Cx26), are a major cause of nonsyndromic recessive hearing loss in many countries and are largely dependent on ethnic groups. The purpose of our study was to characterize the type and prevalence of GJB2 mutations among Azeri population of Iran. M...
متن کاملPrevalence of mitochondrial DNA mutations in sporadic patients with nonsyndromic sensorineural hearing loss.
INTRODUCTION Several mitochondrial DNA mutations have been reported to be associated with nonsyndromic hearing loss in several families. However, little is known about the prevalence of these mutations in sporadic patients with nonsyndromic sensorineural hearing loss. OBJECTIVE The purpose of our study was to investigate the incidence of these mitochondrial DNA mutations in such population. ...
متن کاملMolecular analysis of mitochondrial gene mutations in Korean patients with nonsyndromic hearing loss.
Mutations in mitochondrial DNA (mtDNA) are a major cause of hearing loss. In this study, we performed a systematic mutational screening of the 12S rRNA, tRNA Ser(UCN), tRNA Lys and tRNA Leu(UUR) genes in 227 unrelated patients with nonsyndromic hearing impairment for the first time in a Korean population. We found two individuals with an A1555G mutation, which is a frequency (0.9%) lower than t...
متن کاملStudy on KAL1 Gene Mutations in Idiopathic Hypogonadotropic Hypogonadism Patients with X-Linked Recessive Inheritance
Idiopathic hypogonadotropic hypogonadism (IHH) is a condition caused by low doses of hypothalamic gonadotropin-releasing hormone (GnRH) leading to absence or incomplete sexual maturation. One of the disorders leading to IHH is Kallmann syndrome which is characterized by GnRH deficiency with anosmia or hyposmia. This disorder generally occurs as a hereditary syndrome with X-linked recessive inhe...
متن کاملCASE REPORT 46,XY Hypergonadotropic hypogonadism and myasthenia gravis
Both hypergonadotropic hypogonadism and myasthenia gravis can be parts of type II autoimmune polyendocrine syndrome and association between the two disorders has been reported in few cases. A 14 year old male patient with a personal history of bilateral cryptorchidism and ptosis was referred for delayed puberty. Clinical examination revealed eunuchoid habitus, small, soft testes, gynecomastia, ...
