Labcorp Genetics (formerly Invitae), Labcorp RCV005200770 SCV005835212 likely pathogenic not provided 2024-08-15 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 231 of the LMX1B protein (p.Arg231Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with nail-patella syndrome (PMID: 20531206; Invitae). In at least one individual the variant was observed to be de novo. This variant is also known as c.623G>C; p.R208P. Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt LMX1B protein function with a positive predictive value of 80%. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
