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.

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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬† is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1969533). This variant has not been reported in the literature in individuals affected with MICAL1-related conditions. This variant is present in population databases (rs368885343, gnomAD 0.004%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1068 of the MICAL1 protein (p.Arg1068His). -
