Ocular coloboma
Gene: YAP1Recorded 'incomplete penetrance' for YAP based on two papers: In Oatts et al., 2016 (PMID:27267789) the heterozygous mutation F95S was found in both affected half brothers, as well as their unaffected mother. In family 1305 in Williamson et al., 2014 (PMID:24462371) the R124X mutation was inherited from an unaffected grandfather. Plus clinical information that incomplete penetrance is often seen for ocular coloboma.Created: 2 Feb 2017, 9:29 a.m.

This gene causes coloboma in both humans and zebrafish. This gene was identified via exome sequencing but segregation in the families gave a combined LOD score of >4. The phenotype can be complex in humans with one family in the paper having isolated coloboma and the other having syndromal coloboma with clefting, ID, nonprogressive nephrophathy and deafness. This complexity relates to the different transciptional start sites in the gene that can make stop codons have differential effects depending on their position in the geneCreated: 3 Dec 2016, 11:30 p.m.
