Genes affected

MIOX (HGNC:14522): (myo-inositol oxygenase) Enables ferric iron binding activity and inositol oxygenase activity. Involved in inositol catabolic process. Predicted to be located in cytoplasm and inclusion body. [provided by Alliance of Genome Resources, Apr 2022]

MIOX links:

ADM2 (HGNC:28898): (adrenomedullin 2) This gene encodes a member of the calcitonin gene-related peptide (CGRP)/calcitonin family of hormones that play a role in the regulation of cardiovascular homeostasis, prolactin release, anti-diuresis, anti-natriuresis, and regulation of food and water intake. The encoded protein is proteolytically processed to generate one or more biologically active peptides. [provided by RefSeq, Jul 2015]
