Genes affected

ALOX12B (HGNC:430): (arachidonate 12-lipoxygenase, 12R type) This gene encodes an enzyme involved in the conversion of arachidonic acid to 12R-hydroxyeicosatetraenoic acid. Mutations in this gene are associated with nonbullous congenital ichthyosiform erythroderma. [provided by RefSeq, Sep 2015]

The c.1941C>G (p.H647Q) alteration is located in exon 15 (coding exon 15) of the ALOX12B gene. This alteration results from a C to G substitution at nucleotide position 1941, causing the histidine (H) at amino acid position 647 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
