The variant allele was found at a frequency of 0.372 in 151,924 control chromosomes in the GnomAD database, including 14,818 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.37 (14818 hom., cov: 32)
• Consequence: LMLN NM_001136049.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.42

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.745 is higher than 0.05.
