Genes affected

P3H3 (HGNC:19318): (prolyl 3-hydroxylase 3) The protein encoded by this gene belongs to the leprecan family of proteoglycans, which function as collagen prolyl hydroxylases that are required for proper collagen biosynthesis, folding and assembly. This protein, like other family members, is thought to reside in the endoplasmic reticulum. Epigenetic inactivation of this gene is associated with breast and other cancers, suggesting that it may function as a tumor suppressor. [provided by RefSeq, Aug 2013]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0015980005).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.379 is higher than 0.05.
