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.923G>A (p.R308H) alteration is located in exon 6 (coding exon 6) of the PCNX1 gene. This alteration results from a G to A substitution at nucleotide position 923, causing the arginine (R) at amino acid position 308 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
