Invitae | RCV000467437 | SCV000549941 | uncertain significance | Holoprosencephaly sequence | 2018-04-09 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid with asparagine at codon 342 of the FOXH1 protein (p.Asp342Asn). The aspartic acid residue is moderately conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs536501327, ExAC 0.002%) but has not been reported in the literature in individuals with a FOXH1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. |
