Genes affected

PCDH7 (HGNC:8659): (protocadherin 7) This gene belongs to the protocadherin gene family, a subfamily of the cadherin superfamily. The gene encodes a protein with an extracellular domain containing 7 cadherin repeats. The gene product is an integral membrane protein that is thought to function in cell-cell recognition and adhesion. Alternative splicing yields isoforms with unique cytoplasmic tails.

The c.685T>G (p.S229A) alteration is located in exon 1 (coding exon 1) of the PCDH7 gene. This alteration results from a T to G substitution at nucleotide position 685, causing the serine (S) at amino acid position 229 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
