Genes affected

LANCL1 (HGNC:6508): (LanC like glutathione S-transferase 1) This gene encodes a loosely associated peripheral membrane protein related to the LanC family of bacterial membrane-associated proteins involved in the biosynthesis of antimicrobial peptides. This protein may play a role as a peptide-modifying enzyme component in eukaryotic cells. Previously considered a member of the G-protein-coupled receptor superfamily, this protein is now in the LanC family. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Nov 2008]

Ambry Genetics

Oct 12, 2021

The c.397T>C (p.C133R) alteration is located in exon 4 (coding exon 3) of the LANCL1 gene. This alteration results from a T to C substitution at nucleotide position 397, causing the cysteine (C) at amino acid position 133 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
