Genes affected

MICAL1 (HGNC:20619): (microtubule associated monooxygenase, calponin and LIM domain containing 1) This gene encodes an enzyme that oxidizes methionine residues on actin, thereby promoting depolymerization of actin filaments. This protein interacts with and regulates signalling by NEDD9/CAS-L (neural precursor cell expressed, developmentally down-regulated 9). Alternative splicing results in multiple transcript variants.

This variant has not been reported in the literature in individuals affected with MICAL1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 1056 of the MICAL1 protein (p.Leu1056Pro). 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. -
