RCV000702087 | SCV000830921 | uncertain significance | Kufor-Rakeb syndrome; Autosomal recessive spastic paraplegia type 78 | 2023-07-14 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 544 of the ATP13A2 protein (p.Arg544Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with ATP13A2-related conditions. ClinVar contains an entry for this variant (Variation ID: 578934). 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 ATP13A2 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. |
| Ambry Genetics | RCV002533645 | SCV003550156 | uncertain significance | Inborn genetic diseases | 2022-04-07 | criteria provided, single submitter | clinical testing | The c.1630C>T (p.R544C) alteration is located in exon 16 (coding exon 16) of the ATP13A2 gene. This alteration results from a C to T substitution at nucleotide position 1630, causing the arginine (R) at amino acid position 544 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
