Genes affected

PAN3 (HGNC:29991): (poly(A) specific ribonuclease subunit PAN3) Contributes to poly(A)-specific ribonuclease activity. Predicted to be involved in nuclear-transcribed mRNA poly(A) tail shortening. Predicted to act upstream of or within deadenylation-dependent decapping of nuclear-transcribed mRNA; positive regulation of cytoplasmic mRNA processing body assembly; and protein targeting. Part of PAN complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.262C>G (p.L88V) alteration is located in exon 1 (coding exon 1) of the PAN3 gene. This alteration results from a C to G substitution at nucleotide position 262, causing the leucine (L) at amino acid position 88 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
