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.

The c.3120G>T (p.L1040F) alteration is located in exon 25 (coding exon 24) of the MICAL1 gene. This alteration results from a G to T substitution at nucleotide position 3120, causing the leucine (L) at amino acid position 1040 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
