Genes affected

LCA5 (HGNC:31923): (lebercilin LCA5) This gene encodes a protein that is thought to be involved in centrosomal or ciliary functions. Mutations in this gene cause Leber congenital amaurosis type V. Alternatively spliced transcript variants are described. [provided by RefSeq, Oct 2009]

LCA5 links:

SH3BGRL2 (HGNC:15567): (SH3 domain binding glutamate rich protein like 2) Predicted to enable SH3 domain binding activity. Located in nuclear membrane and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
