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

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0053784847).
• BP6: Variant 13-43881097-A-G is Benign according to our data. Variant chr13-43881097-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 721083.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr13-43881097-A-G is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00483 (736/152348) while in subpopulation SAS AF= 0.0058 (28/4830). AF 95% confidence interval is 0.00429. There are 6 homozygotes in gnomad4. There are 429 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 6 AR gene
