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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 16, 2021The c.12G>C (p.Q4H) alteration is located in exon 1 (coding exon 1) of the PCNX1 gene. This alteration results from a G to C substitution at nucleotide position 12, causing the glutamine (Q) at amino acid position 4 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
