Invitae | RCV000811211 | SCV000951466 | uncertain significance | Jeune thoracic dystrophy; Nephronophthisis | 2018-09-11 | criteria provided, single submitter | clinical testing | 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. 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: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with TTC21B-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with aspartic acid at codon 1065 of the TTC21B protein (p.Glu1065Asp). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and aspartic acid. |
