Labcorp Genetics (formerly Invitae), Labcorp RCV001935378 SCV002185719 uncertain significance Hypoplastic enamel-onycholysis-hypohidrosis syndrome 2021-07-17 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 variant disrupts the C-terminus of the MSX1 protein. Other variant(s) that disrupt this region (p.Phe251*, p.Ala282Argfs*21) have been observed in individuals with MSX1-related conditions (PMID: 27917906; Invitae). This suggests that this may be a clinically significant region of the protein. This premature translational stop signal has been observed in individual(s) with oligodontia (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Pro248Serfs*13) in the MSX1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 56 amino acid(s) of the MSX1 protein.
