Genes affected

CECR2 (HGNC:1840): (CECR2 histone acetyl-lysine reader) This gene encodes a bromodomain-containing protein that is involved in chromatin remodeling, and may additionally play a role in DNA damage response. The encoded protein functions as part of an ATP-dependent complex that is involved in neurulation. This gene is a candidate gene for Cat Eye Syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]

ENSG00000286195 (HGNC:):

ACMG classification
