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.

Ambry Genetics

Aug 12, 2021

The c.96G>C (p.Q32H) alteration is located in exon 1 (coding exon 1) of the PCDH7 gene. This alteration results from a G to C substitution at nucleotide position 96, causing the glutamine (Q) at amino acid position 32 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
