Genes affected

PCDHB6 (HGNC:8691): (protocadherin beta 6) This gene is a member of the protocadherin beta gene cluster, one of three related gene clusters tandemly linked on chromosome five. The gene clusters demonstrate an unusual genomic organization similar to that of B-cell and T-cell receptor gene clusters. Unlike the alpha and gamma clusters, the transcripts from these genes do not share common 3' exons. These neural cadherin-like cell adhesion proteins are integral plasma membrane proteins that most likely play a critical role in the establishment and function of specific cell-cell neural connections. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

Jun 27, 2023

The c.815C>G (p.S272W) alteration is located in exon 1 (coding exon 1) of the PCDHB6 gene. This alteration results from a C to G substitution at nucleotide position 815, causing the serine (S) at amino acid position 272 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
