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.

PAN2 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 4 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.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.83

The c.2905C>T (p.P969S) alteration is located in exon 21 (coding exon 20) of the PAN2 gene. This alteration results from a C to T substitution at nucleotide position 2905, causing the proline (P) at amino acid position 969 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
