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]

The c.88C>T (p.R30C) alteration is located in exon 1 (coding exon 1) of the LMLN gene. This alteration results from a C to T substitution at nucleotide position 88, causing the arginine (R) at amino acid position 30 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
