The variant allele was found at a frequency of 0.271 in 152,100 control chromosomes in the GnomAD database, including 7,496 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.27 (7496 hom., cov: 32)
• Consequence: PCNX2 NM_014801.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.260

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.513 is higher than 0.05.
