• Clinical Significance: Likely benign criteria provided, single submitter B:1
• Conservation: PhyloP100: 3.39

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 Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.04169312).
• BP6: Variant 15-44668431-G-A is Benign according to our data. Variant chr15-44668431-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2269926.Status of the report is criteria_provided_single_submitter, 1 stars.

Ambry Genetics

Jan 04, 2022

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
