Genes affected

PCDH17 (HGNC:14267): (protocadherin 17) This gene belongs to the protocadherin gene family, a subfamily of the cadherin superfamily. The encoded protein contains six extracellular cadherin domains, a transmembrane domain, and a cytoplasmic tail differing from those of the classical cadherins. The encoded protein may play a role in the establishment and function of specific cell-cell connections in the brain. [provided by RefSeq, Jul 2008]

Mar 14, 2023

The c.901G>A (p.G301S) alteration is located in exon 1 (coding exon 1) of the PCDH17 gene. This alteration results from a G to A substitution at nucleotide position 901, causing the glycine (G) at amino acid position 301 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
