Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 10P and 1B. PM2PP5_Very_StrongBP4

The NM_003560.4(PLA2G6):c.1435C>G(p.His479Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000213 in 1,406,660 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H479Y) has been classified as Uncertain significance.

Genes affected

PLA2G6 (HGNC:9039): (phospholipase A2 group VI) The protein encoded by this gene is an A2 phospholipase, a class of enzyme that catalyzes the release of fatty acids from phospholipids. The encoded protein may play a role in phospholipid remodelling, arachidonic acid release, leukotriene and prostaglandin synthesis, fas-mediated apoptosis, and transmembrane ion flux in glucose-stimulated B-cells. Several transcript variants encoding multiple isoforms have been described, but the full-length nature of only three of them have been determined to date. [provided by RefSeq, Dec 2010]

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The variant is not observed in the gnomAD v2.1.1 dataset. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.12; 3Cnet: 0.89). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with PLA2G6- related disorder (ClinVar ID: VCV000529507 / PMID: 30340910). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 30340910). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces histidine, which is basic and polar, with aspartic acid, which is acidic and polar, at codon 479 of the PLA2G6 protein (p.His479Asp). This variant is present in population databases (no rsID available, gnomAD 0.001%). This missense change has been observed in individual(s) with clinical features of PLA2G6-related conditions (PMID: 30340910; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 529507). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PLA2G6 protein function with a negative predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: PLA2G6 c.1435C>G (p.His479Asp) results in a non-conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change. The variant allele was found at a frequency of 1.9e-06 in 1558980 control chromosomes. c.1435C>G has been observed in individuals affected with PLA2G6-associated neurodegeneration (Darling_2019, Vela-Desojo_2022, Labcorp (formerly Invitae)). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 30340910, 35329915). ClinVar contains an entry for this variant (Variation ID: 529507). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
