Genes affected

PYM1 (HGNC:30258): (PYM homolog 1, exon junction complex associated factor) Enables ribosome binding activity. Involved in exon-exon junction complex disassembly; nuclear-transcribed mRNA catabolic process, nonsense-mediated decay; and positive regulation of translation. Located in cell junction; cytosol; and nuclear lumen. Part of exon-exon junction complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.12429598).
• BS2: High AC in GnomAdExome4 at 6 AD gene.
