Genes affected

PCNX1 (HGNC:19740): (pecanex 1) This gene encodes an evolutionarily conserved transmembrane protein similar to the pecanex protein in Drosophila. The fly protein is a component of the Notch signaling pathway, which functions in several developmental processes. [provided by RefSeq, Jul 2016]

Ambry Genetics

Nov 08, 2021

The c.761C>G (p.S254C) alteration is located in exon 6 (coding exon 6) of the PCNX1 gene. This alteration results from a C to G substitution at nucleotide position 761, causing the serine (S) at amino acid position 254 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
