Genes affected

MIR497HG (HGNC:39523): (mir-497-195 cluster host gene)

ALOX12-AS1 (HGNC:51342): (ALOX12 antisense RNA 1)

ALOX12 (HGNC:429): (arachidonate 12-lipoxygenase, 12S type) This gene encodes a member of the lipoxygenase family of proteins. The encoded enzyme acts on different polyunsaturated fatty acid substrates to generate bioactive lipid mediators including eicosanoids and lipoxins. The encoded enzyme and its reaction products have been shown to regulate platelet function. Elevated expression of this gene has been observed in pancreatic islets derived from human diabetes patients. Allelic variants in this gene may be associated with susceptibility to toxoplasmosis. Multiple pseudogenes of this gene have been identified in the human genome. [provided by RefSeq, Aug 2017]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BP6: Variant 17-6995799-C-T is Benign according to our data. Variant chr17-6995799-C-T is described in ClinVar as Benign. ClinVar VariationId is 1269983.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.502 is higher than 0.05.
