RCV002478012 | SCV002605550 | likely pathogenic | COACH syndrome 1 | 2022-04-12 | criteria provided, single submitter | clinical testing | This variant is predicted to result in a single amino acid substitution of Arg to Gly at codon 792 in exon 23 of the TMEM67 gene. It was found in trans with a second TMEM67 variant in a patient with features of COACH syndrome. This variant meets the following ACMG criteria: PM2, PM3, PP2, PP3. |

RCV003772169 | SCV004582054 | likely pathogenic | Familial aplasia of the vermis; Meckel-Gruber syndrome | 2023-12-01 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 792 of the TMEM67 protein (p.Arg792Gly). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Joubert syndrome and related disorders and/or nephronophthisis (PMID: 21068128, 36617405). ClinVar contains an entry for this variant (Variation ID: 1325829). 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 TMEM67 protein function with a positive predictive value of 95%. 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. |
