Homo sapiens

Also known as FSGS9; VMCKD

Gene ID: 286204 | Gene type: protein coding

About CRB2

Cytogenetic location: 9q33.3 Genomic coordinates (GRCh38): 9:123,354,065-123,380,326 (from NCBI)

This gene has 3 transcripts (splice variants), 234 orthologues, 3 paralogues and is associated with 6 phenotypes. Broad expression in brain (RPKM 3.7), kidney (RPKM 3.4) and 23 other tissues.

Summary

This gene encodes a member of a family of proteins that are components of the Crumbs cell polarity complex. In mammals, members of this family are thought to play a role in many cellular processes in early embryonic development. A similar protein in Drosophila determines apicobasal polarity in embryonic epithelial cells. Mutations in this gene are associated with focal segmental glomerulosclerosis 9, and with ventriculomegaly with cystic kidney disease. [provided by RefSeq, Aug 2016]
