Baylor Genetics RCV001293878 SCV001482540 uncertain significance Chondrosarcoma 2020-02-12 criteria provided, single submitter clinical testing This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868].
Labcorp Genetics (formerly Invitae), Labcorp RCV002543022 SCV002968955 uncertain significance Multiple congenital exostosis 2022-09-05 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 aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 291 of the EXT1 protein (p.Asp291Glu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with EXT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 998182). 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 EXT1 protein function.
3billion RCV004727087 SCV005328732 likely benign Exostoses, multiple, type 1 2024-09-20 criteria provided, single submitter clinical testing The variant was identified in at least one patient who was diagnosed with a different variant in another gene and showed no symptoms related to the gene containing the variant in question.
