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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.353A>T (p.K118M) alteration is located in exon 4 (coding exon 4) of the LMLN gene. This alteration results from a A to T substitution at nucleotide position 353, causing the lysine (K) at amino acid position 118 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
