Genes affected

PCDH12 (HGNC:8657): (protocadherin 12) This gene belongs to the protocadherin gene family, a subfamily of the cadherin superfamily. The encoded protein consists of an extracellular domain containing 6 cadherin repeats, a transmembrane domain and a cytoplasmic tail that differs from those of the classical cadherins. The gene localizes to the region on chromosome 5 where the protocadherin gene clusters reside. The exon organization of this transcript is similar to that of the gene cluster transcripts, notably the first large exon, but no significant sequence homology exists. The function of this cellular adhesion protein is undetermined but mouse protocadherin 12 does not bind catenins and appears to have no affect on cell migration or growth.

DELE1 (HGNC:28969): (DAP3 binding cell death enhancer 1) Enables protein kinase binding activity and protein serine/threonine kinase activator activity. Involved in HRI-mediated signaling; extrinsic apoptotic signaling pathway via death domain receptors; and regulation of cysteine-type endopeptidase activity involved in apoptotic process. Located in cytosol and mitochondrial inner membrane. [provided by Alliance of Genome Resources, Apr 2022]
