Genes affected
LACC1 (HGNC:26789): (laccase domain containing 1) This gene encodes an oxidoreductase that promotes fatty-acid oxidation, with concomitant inflammasome activation, mitochondrial and NADPH-oxidase-dependent reactive oxygen species production, and bactericidal activity of macrophages. The encoded protein forms a complex with fatty acid synthase on peroxisomes and is thought to be modulated by peroxisome proliferator-activated receptor signaling events. Naturally occurring mutations in this gene are associated with inflammatory bowel disease, Behcet's disease, leprosy, ulcerative colitis, early-onset Crohn's disease, and systemic juvenile idiopathic arthritis.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

PM2
?
    PM2 - Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium
Very rare variant in population databases, with high coverage;
BP4
?
    BP4 - Multiple lines of computational evidence suggest no impact on gene or gene product (conservation, evolutionary, splicing impact, etc.)
Computational evidence support a benign effect (BayesDel_noAF=-0.9).
BP6
?
    BP6 - Reputable source recently reports variant as benign, but the evidence is not available to the laboratory to perform an independent evaluation
Variant 13-43881408-G-A is Benign according to our data. Variant chr13-43881408-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 743333.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
?
    BP7 - A synonymous (silent) variant for which splicing prediction algorithms predict no impact to the splice consensus sequence nor the creation of a new splice site AND the nucleotide is not highly conserved
Synonymous conserved (PhyloP=-0.039 with no splicing effect.
BS1
?
    BS1 - Allele frequency is greater than expected for disorder
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000438 (64/1461794) while in subpopulation MID AF= 0.000693 (4/5768). AF 95% confidence interval is 0.000236. There are 0 homozygotes in gnomad4_exome. There are 26 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
