Genes affected

PATL2 (HGNC:33630): (PAT1 homolog 2) Predicted to enable RNA binding activity. Predicted to be involved in P-body assembly and deadenylation-dependent decapping of nuclear-transcribed mRNA. Predicted to act upstream of or within negative regulation of cytoplasmic mRNA processing body assembly. Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
