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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2024The c.2581G>T (p.D861Y) alteration is located in exon 18 (coding exon 17) of the PAN2 gene. This alteration results from a G to T substitution at nucleotide position 2581, causing the aspartic acid (D) at amino acid position 861 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
