Recently, we and others have shown that mutations in TMPRSS3 were responsible for autosomal recessive non-syndromic hearing loss. TMPRSS3 is a member of the Type II Transmembrane Serine Protease (TTSP) family and encodes for a protease that also contains LDLRA (low-density lipoprotein receptor class A) and SRCR (scavenger receptor cysteine rich) domains. Fourteen pathogenic mutations, which occ...

Mutations in the human GJB2 gene, which encodes connexin26 (Cx26), underlie various forms of hereditary deafness and skin disease. While it has proven difficult to discern the exact pathological mechanisms that cause these disorders, studies have shown that the loss or abnormal function of Cx26 protein has a profound effect on tissue homeostasis. Here, we used the Xenopus oocyte expression syst...

Mutations in the gene of connexin 26 (Cx26) are the most common cause of human non‑syndromic hereditary deafness. The pathogenesis of deafness caused by Cx26 remains uncertain. To explore the basic mechanism underlying Cx26 null mutations, ultrastructural changes and a number of marker proteins in the cochlear sensory epithelium of Cx26 conditional knockout mice were observed in the current stu...

Mutations in myosin VI have been associated with autosomal-recessive (DFNB37) and autosomal-dominant (DFNA22) deafness in humans. Here, we characterise an myosin VI nonsense mutation (R1166X) that was identified in a family with hereditary hearing loss in Pakistan. This mutation leads to the deletion of the C-terminal 120 amino acids of the myosin VI cargo-binding domain, which includes the WWY...

discussion similar resilience scores in deaf and hearing participants may be due to appropriate interaction of deaf signers with family members and society. male deaf subjects were more resilient than female ones; studies should be done to examine the effects of cultural characteristics that may provide females with less communication opportunities than males. materials and methods this compara...

We studied a family with hereditary sensory motor neuropathy and deafness accompanying a missense mutation in the MPZ gene. Pathological examination of the cochlea in one of the family members revealed marked loss of auditory ganglion cells and central and peripheral auditory nerve fibres within the cochlea. The inner hair cells were of normal number with preserved morphology. The outer hair ce...

Vohwinkel Syndrome (VS) is a type of diffuse hereditary palmoplantar keratodermas (DHPPK) accompanied by skeletal dimorphisms and sensorineural deafness. The most frequently reported genetic substrate in VS is a point mutation of GJB2 gene, responsible for encoding connexin 26, a gap-junction protein with a crucial role in neuronal migration in rats. We report the case of a 21-year-old male who...

Hereditary benign telangiectasia is an uncommon idiopathic skin disorder characterized by generalized telangiectases and angiomatous lesions of the skin. The diagnosis should be suspected in patients with such cutaneous lesions, positive family history, no associated bleeding problems, and no mucosal involvement. We present six cases of hereditary benign telangiectasia in three generations of o...

This is an article about children's deafness, it's ethiology, diagnosis, treatment, and educa­tional treatment. Here I have given a brief account about the deafness itself and it's in­dividual and social complications, also it's im­pression on the psychological well baing of the child. Then I have discussed, rather in detail, the ethiology of .children's deafness and I have given some statistic...
