Invitae RCV001243132 SCV001416268 uncertain significance Saldino-Mainzer syndrome 2022-09-27 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 670 of the IFT140 protein (p.Pro670Leu). This variant is present in population databases (rs149845330, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with IFT140-related conditions. ClinVar contains an entry for this variant (Variation ID: 968079). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt IFT140 protein function. 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.
