The NM_001355008.2(MMP24-AS1-EDEM2):c.-102+16473G>C variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: NM_001355008.2 is not a MANE Select or MANE Plus Clinical transcript for MMP24-AS1-EDEM2; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. The variant has a gnomAD grpmax filtering allele frequency (95% CI) of 0.0000147, indicating it is observed in the general population. Note: a gnomAD entry for this variant shows a statistical allele-bias signature, consistent with mosaic/somatic contamination (e.g. age-related clonal hematopoiesis) rather than true inherited population frequency — this frequency should not be read as evidence of a common, benign germline variant. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

MMP24-AS1-EDEM2 (HGNC:):

PROCR (HGNC:9452): (protein C receptor) The protein encoded by this gene is a receptor for activated protein C, a serine protease activated by and involved in the blood coagulation pathway. The encoded protein is an N-glycosylated type I membrane protein that enhances the activation of protein C. Mutations in this gene have been associated with venous thromboembolism and myocardial infarction, as well as with late fetal loss during pregnancy. The encoded protein may also play a role in malarial infection and has been associated with cancer. [provided by RefSeq, Jul 2013]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -2 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	PM2Absent/extremely low in population databases		Very rare in gnomAD for AR/unknown gene (popmax AF < threshold/10) — PM2; GnomAD popmax AF = 0.0000147 — very rare for unknown gene (threshold 0.001) — PM2 moderate.
	BP4Computational evidence suggests no impact		Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); No splicing predictor data available.; Germline computational verdict: benign (Strong).
