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]

The c.410T>C (p.M137T) alteration is located in exon 1 (coding exon 1) of the PCDHB6 gene. This alteration results from a T to C substitution at nucleotide position 410, causing the methionine (M) at amino acid position 137 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
