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]

PATL2 Gene-Disease associations (from GenCC):

• oocyte maturation defect 4

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
