Oocyte maturation defect 4 Pathogenic:3
Apr 16, 2018
SIB Swiss Institute of Bioinformatics
Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:curation

This variant is interpreted as a Likely Pathogenic, for Oocyte maturation defect 4, Autosomal Recessive inheritance. The following ACMG Tag(s) were applied: PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP1 => Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease. PS3-Moderate => PS3 downgraded in strength to Moderate (PMID:28965844). PVS1-Strong => PVS1 downgraded in strength to Strong (PMID:28965844). -

Oocyte maturation defect 2 Pathogenic:1
Apr 02, 2021
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine
Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Arg160X variant in PATL2 has been reported as homozygous in 8 Middle Eastern and North African women with oocyte maturation arrest and segregated with disease in 1 affected individual from 1 family (Maddirevula 2017 PMID: 28965844, Christou-Kent 2018 PMID: 29661911, Okutman 2021 PMCID: PMC7999157). This variant has also been reported by other clinical laboratories in ClinVar (Variation ID: 444045) and has also been identified in 0.003% (3/154084) of pan-ethnic chromosomes by gnomAD (http://gnomad.broadinstitute.org). This nonsense variant leads to a premature termination codon at position 160, which is predicted to lead to a truncated or absent protein. Loss of function of the PATL2 gene is strongly associated to autosomal recessive oocyte maturation arrest. In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal recessive oocyte maturation arrest. ACMG/AMP Criteria applied: PVS1_Strong, PM3, PM2_Supporting. -
