Genes affected
PAN2 (HGNC:20074): (poly(A) specific ribonuclease subunit PAN2) This gene encodes a deadenylase that functions as the catalytic subunit of the polyadenylate binding protein dependent poly(A) nuclease complex. The encoded protein is a magnesium dependent 3' to 5' exoribonuclease that is involved in the degradation of cytoplasmic mRNAs. Alternate splicing results in multiple transcript variants.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PAN2. . Gene score misZ 3.1762 (greater than the threshold 3.09). Trascript score misZ 4.8346 (greater than threshold 3.09). GenCC has associacion of gene with multiple congenital anomalies/dysmorphic syndrome-intellectual disability.
BP4
Computational evidence support a benign effect (MetaRNN=0.35581106).
