Variant summary

Our verdict is . The variant received -3 ACMG points: 2P and 5B. PM2BS2BP4

The NM_000698.5(ALOX5):c.347G>A (p.Arg116His) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.00000683 (AC=11) in the gnomAD database across 1,611,238 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.00000799. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.R116C: Uncertain_significance (ClinVar VariationId 4275937, 1 star)

Genes affected

ALOX5 (HGNC:435): (arachidonate 5-lipoxygenase) This gene encodes a member of the lipoxygenase gene family and plays a dual role in the synthesis of leukotrienes from arachidonic acid. The encoded protein, which is expressed specifically in bone marrow-derived cells, catalyzes the conversion of arachidonic acid to 5(S)-hydroperoxy-6-trans-8,11,14-cis-eicosatetraenoic acid, and further to the allylic epoxide 5(S)-trans-7,9-trans-11,14-cis-eicosatetrenoic acid (leukotriene A4). Leukotrienes are important mediators of a number of inflammatory and allergic conditions. Mutations in the promoter region of this gene lead to a diminished response to antileukotriene drugs used in the treatment of asthma and may also be associated with atherosclerosis and several cancers. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PM2

Very rare in gnomAD for AD/XL gene (popmax AF < threshold/10) — PM2; GnomAD popmax AF = 0.00000799 — very rare for AD/XL gene (threshold 0.0001) — PM2 moderate.

BP4

Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Supporting).

BS2

Pure AD gene with cumulative gnomAD AC ≥5 — observed in healthy adults (BS2); GnomAD homozygous count = 0.; Cumulative gnomAD AC = 11 (pure AD gene, not AR).
