It is estimated that hereditary hearing loss accounts for 60% of deafness in the developed countries. About 30% of hereditary hearing impairment is syndromic which involves other presenting abnormalities along with deafness. There are more than 400 syndromes which include various degrees of hearing impairment with different phenotypes. (Barlow Stewart et al., 2007; Berrettini et al., 2008). Abn...
Case report: Congenital disfiguring malformations are rare and usually have a multifactorial aetiology. Here we report on the ocular manifestations seen in a patient with Proteus syndrome. The retina showed retinal dysgenesia, retinal pigmentary abnormalities and optic nerve hypoplasia. Other abnormalities included strabismus and high myopia.

A 1-year-old girl with partial 5q trisomy and partial 7q monosomy had ocular abnormalities that included bilateral blepharoptosis and Leber's congenital amaurosis. A single bright-flash electroretinogram (dark-adapted, white stimulation) disclosed subnormal bilateral responses. Her maculas showed a reddish spot surrounded by a broad, greyish retinal zone.

Early-onset ataxia with ocular motor apraxia and hypoalbuminemia (EAOH) is a neurodegenerative disorder caused by mutation in the aprataxin (APTX)-coding gene APTX, which involved DNA single-strand break repair (SSBR). The neurological abnormalities associated EAOH are similar to those observed patients ataxia-telangiectasia. However, immunological have not been described. In this study, we rep...
