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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 24, 2023 | The c.497A>G (p.N166S) alteration is located in exon 5 (coding exon 4) of the LANCL1 gene. This alteration results from a A to G substitution at nucleotide position 497, causing the asparagine (N) at amino acid position 166 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
