Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM1PM2PM5PP3_ModeratePP5_Very_Strong
The NM_017807.4(OSGEP):c.838C>T(p.Arg280Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000489 in 1,613,934 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R280H) has been classified as Pathogenic.

Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Feb 19, 2022 | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 280 of the OSGEP protein (p.Arg280Cys). This variant is present in population databases (rs374322839, gnomAD 0.006%). This missense change has been observed in individual(s) with Galloway–Mowat syndrome (PMID: 28805828). 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: 444892). 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 (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). Experimental studies have shown that this missense change affects OSGEP function (PMID: 28805828). This variant disrupts the p.Arg280 amino acid residue in OSGEP. Other variant(s) that disrupt this residue have been observed in individuals with OSGEP-related conditions (PMID: 28805828), which suggests that this may be a clinically significant amino acid residue. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. - |
