Labcorp Genetics (formerly Invitae), Labcorp RCV001989459 SCV002285513 uncertain significance Surfactant metabolism dysfunction, pulmonary, 4 2021-04-23 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. This sequence change replaces valine with isoleucine at codon 341 of the CSF2RA protein (p.Val341Ile). The valine residue is weakly conserved and there is a small physicochemical difference between valine and isoleucine. This variant is present in population databases (no rsID available, ExAC 0.001%). This variant has not been reported in the literature in individuals with CSF2RA-related conditions. 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 isoleucine 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.
