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: "Deleterious"; PolyPhen-2: "Not available"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with LDB3-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with leucine at codon 635 of the LDB3 protein (p.Val635Leu). The valine residue is highly conserved and there is a small physicochemical difference between valine and leucine. The LDB3 gene has multiple clinically relevant transcripts. The p.Val635Leu variant occurs in alternate transcript NM_007078.2, which corresponds to position c.*19398G>C in NM_001080116.1:, the primary transcript listed in the Methods. |
