Invitae | RCV000810803 | SCV000951037 | uncertain significance | Familial aplasia of the vermis; Meckel-Gruber syndrome | 2021-08-27 | criteria provided, single submitter | clinical testing | This sequence change replaces cysteine with tyrosine at codon 784 of the TMEM67 protein (p.Cys784Tyr). The cysteine residue is moderately conserved and there is a large physicochemical difference between cysteine and tyrosine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with TMEM67-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. |
