Genes affected

LMLN (HGNC:15991): (leishmanolysin like peptidase) This gene encodes a zinc-metallopeptidase. The encoded protein may play a role in cell migration and invasion. Studies of a similar protein in Drosophila indicate a potential role in mitotic progression. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2009]

Ambry Genetics

Oct 20, 2023

The c.992G>A (p.R331Q) alteration is located in exon 9 (coding exon 9) of the LMLN gene. This alteration results from a G to A substitution at nucleotide position 992, causing the arginine (R) at amino acid position 331 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
