RCV002515978 | SCV003761472 | pathogenic | PLA2G6-associated neurodegeneration | 2023-01-24 | criteria provided, single submitter | curation | The p.Gln700Ter variant in PLA2G6 has been reported in 2 individuals with PLA2G6-associated neurodegeneration (PMID: 27848944, 23100014) and has been identified in 0.0009% (1/113726) of European (non-Finnish) chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP ID: rs587784346). Although this variant has been seen in the general population in a heterozygous state, its frequency is low enough to be consistent with a recessive carrier frequency. This variant has also been reported in ClinVar (Variation ID#: 159758) and has been interpreted as pathogenic by Genetic Services Laboratory (University of Chicago) and PerkinElmer Genomics. Of the 2 affected individuals, both of them were homozygotes, which increases the likelihood that the p.Gln700Ter variant is pathogenic (PMID: 27848944, 23100014). This nonsense variant leads to a premature termination codon at position 700, which is predicted to lead to a truncated or absent protein. Loss of function of the PLA2G6 gene is an established disease mechanism in autosomal recessive PLA2G6-associated neurodegeneration. In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive PLA2G6-associated neurodegeneration. ACMG/AMP Criteria applied: PVS1, PM3, PM2_supporting (Richards 2015). |

RCV003507258 | SCV004300018 | pathogenic | Infantile neuroaxonal dystrophy | 2024-01-04 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Gln700*) in the PLA2G6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PLA2G6 are known to be pathogenic (PMID: 16783378, 18570303, 18799783, 22213678). This variant is present in population databases (rs587784346, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with PLA2G6-related conditions (PMID: 27848944). ClinVar contains an entry for this variant (Variation ID: 159758). For these reasons, this variant has been classified as Pathogenic. |
