Other human magnesium genetic transport disorders are the isolated autosomal recessive hypomagnesemia (gene: Epidermal Growth Factor/EGF), autosomal dominant hypomagnesemia (gene: potassium channel, voltage gated shaker related subfamily A, member 1/KCNA1), Gitelman syndrome (gene: Na-Cl-Co-transporter/NCC), isolated dominant hypomagnesemia (gene: Na+/K+-ATPase), maturity-onset diabetes of young (gene: Hepatocyte Nuclear Factor-1 Beta/HNF1B), and the SeSAME syndrome (gene: potassium channel, inwardly rectifying subfamily J, member 10/KCNJ10) [15,37]. The gene discussed is EGF; the disease is maturity-onset diabetes of the young.
