Invitae	RCV001701490	SCV003443913	likely pathogenic	not provided	2022-03-21	criteria provided, single submitter	clinical testing	This missense change has been observed in individuals with steroid-resistant nephrotic syndrome (PMID: 24270420, 28204945, 28454995, 29382012, 31130284, 31937884, 32543055, 32604935, 32859164). It has also been observed to segregate with disease in related individuals. 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. Experimental studies have shown that this missense change affects COQ8B function (PMID: 29194833). 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 COQ8B protein function. ClinVar contains an entry for this variant (Variation ID: 91845). 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 sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 178 of the COQ8B protein (p.Arg178Trp).
