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 5 ACMG points.

PM1
In a modified_residue Phosphoserine (size 0) in uniprot entity PAN2_HUMAN
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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.3578C>T (p.A1193V) alteration is located in exon 26 (coding exon 25) of the PAN2 gene. This alteration results from a C to T substitution at nucleotide position 3578, causing the alanine (A) at amino acid position 1193 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
