Invitae | RCV001040356 | SCV001203924 | uncertain significance | Familial aplasia of the vermis; Meckel-Gruber syndrome | 2019-04-15 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with TCTN1-related conditions. This variant is present in population databases (rs748298895, ExAC 0.02%). This sequence change replaces aspartic acid with glutamic acid at codon 73 of the TCTN1 protein (p.Asp73Glu). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and glutamic acid. 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. |
