Genes affected

POP1 (HGNC:30129): (POP1 homolog, ribonuclease P/MRP subunit) This gene encodes the protein subunit of two different small nucleolar ribonucleoprotein complexes: the endoribonuclease for mitochondrial RNA processing complex and the ribonuclease P complex. The encoded protein is a ribonuclease that localizes to the nucleus and functions in pre-RNA processing. This protein is also an autoantigen in patients suffering from connective tissue diseases. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.786
• PP5: Variant 8-98148848-C-T is Pathogenic according to our data. Variant chr8-98148848-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 417736.Status of the report is no_assertion_criteria_provided, 0 stars.
