Invitae | RCV000798007 | SCV000937599 | uncertain significance | Adams-Oliver syndrome 5 | 2018-12-12 | criteria provided, single submitter | clinical testing | The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The aspartic acid 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. This variant has not been reported in the literature in individuals with NOTCH1-related conditions. This sequence change replaces alanine with aspartic acid at codon 51 of the NOTCH1 protein (p.Ala51Asp). The alanine residue is moderately conserved and there is a moderate physicochemical difference between alanine and aspartic acid. |
