Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP3_StrongPP5
The NM_003560.4(PLA2G6):c.1978C>T(p.Pro660Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 13/20 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P660R) has been classified as Likely pathogenic.

not provided Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | GeneDx | May 09, 2023 | Has not been previously published as pathogenic or benign to our knowledge; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Not observed at significant frequency in large population cohorts (gnomAD) - |
Infantile neuroaxonal dystrophy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 03, 2021 | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 660 of the PLA2G6 protein (p.Pro660Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PLA2G6-related conditions. ClinVar contains an entry for this variant (Variation ID: 159751). 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 expected to disrupt PLA2G6 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
