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]

The c.2437C>T (p.P813S) alteration is located in exon 7 (coding exon 7) of the PCNX1 gene. This alteration results from a C to T substitution at nucleotide position 2437, causing the proline (P) at amino acid position 813 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
