Ichthyosis linearis circumflexa Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 18, 2018 | This variant has not been reported in the literature in individuals with SPINK5-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with glycine at codon 980 of the SPINK5 protein (p.Asp980Gly). The aspartic acid residue is moderately conserved and there is a moderate physicochemical difference between aspartic acid and glycine. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glycine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. - |
