Genes affected

PITRM1 (HGNC:17663): (pitrilysin metallopeptidase 1) The protein encoded by this gene is an ATP-dependent metalloprotease that degrades post-cleavage mitochondrial transit peptides. The encoded protein binds zinc and can also degrade amyloid beta A4 protein, suggesting a possible role in Alzheimer's disease. [provided by RefSeq, Dec 2016]

PITRM1-AS1 (HGNC:44675): (PITRM1 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004927784).
• BP6: Variant 10-3155664-C-G is Benign according to our data. Variant chr10-3155664-C-G is described in ClinVar as [Benign]. Clinvar id is 1601727.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.283 is higher than 0.05.
