LEOPARD syndrome is an autosomal dominant hereditary disease, which is characterized with cutaneous pigmented patches, electrocardiographic changes, ocular hypertelorism, retarded growth, pulmonic stenosis, genital abnormalities and congenital deafness. The gene of this disease have high penetrance but expression is varied and incomplete forms may be seen. We report a 23 year-old woman wi...

The theory of predictive coding assumes that higher-order representations influence lower-order representations by generating predictions about sensory input. In congenital deafness, one identified dysfunction is a reduced activation of deep layers in the auditory cortex. Since these layers play a central role for processing top-down influences, congenital deafness might interfere with the inte...

Congenital deafness not only affects the development of the auditory cortex, but also the interrelation between the visual and auditory system. For example, congenital deafness leads to visual modulation of the deaf auditory cortex in the form of cross-modal plasticity. Here we asked, whether congenital deafness additionally affects auditory modulation in the visual cortex. We demonstrate that ...

A significantly increased risk for dominant sensorineural deafness in patients who have Hirschsprung disease (HSCR) caused by endothelin receptor type B and SOX10 has been reported. Despite the fact that c-RET is the most frequent causal gene of HSCR, it has not been determined whether impairments of c-Ret and c-RET cause congenital deafness in mice and humans. Here, we show that impaired phosp...

BACKGROUND Congenital sensorineural deafness has been reported frequently in experimental mixed-breed white cats but there is a paucity of data on occurrence of deafness in client-owned pure-breed white cats. OBJECTIVE To describe hearing status in client-owned pure-breed white cats. ANIMALS Eighty-four pure-breed client-owned cats with white coat color of 10 registered breeds presented for...

Admas-Oliver syndrome is a rare autosomal dominant disease of congenital development defects association with aplasia cutis. All of 81 reported cases were of 32 group families. These two cases had congenital scalp cutis aplasia with developmental defect and hypoplasia of left foot digits in case 1.Congenital deaf-mute in both can added to the past known findings in this syndrome. Thoracic defor...
