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.

The 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. -
