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.3574C>G (p.Q1192E) alteration is located in exon 17 (coding exon 17) of the PCNX1 gene. This alteration results from a C to G substitution at nucleotide position 3574, causing the glutamine (Q) at amino acid position 1192 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
