Genes affected
PCNX2 (HGNC:8736): (pecanex 2) This gene contains coding mononucleotide repeats that are associated with tumors of high mcrosatellite instability (MSI-H). Defects in this gene are involved in the tumorigenesis of MSI-H colorectal carcinomas. [provided by RefSeq, Jun 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2021The c.5637T>A (p.S1879R) alteration is located in exon 32 (coding exon 32) of the PCNX2 gene. This alteration results from a T to A substitution at nucleotide position 5637, causing the serine (S) at amino acid position 1879 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
