Genes affected

PCOLCE2 (HGNC:8739): (procollagen C-endopeptidase enhancer 2) Enables collagen binding activity; heparin binding activity; and peptidase activator activity. Predicted to be involved in positive regulation of peptidase activity. Predicted to act upstream of or within cellular response to leukemia inhibitory factor. Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0269 (4101/152246) while in subpopulation NFE AF= 0.0411 (2796/67988). AF 95% confidence interval is 0.0399. There are 86 homozygotes in gnomad4. There are 1987 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 86 AR gene
