Green List (high evidence)

Mode of inheritance
BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal

Variants in this GENE are reported as part of current diagnostic practice

Ellen McDonagh (Genomics England Curator)

From Illumina information for this gene, Pemanent neonatal diabetes mellitus and Transient neonatal diabetes have a recessive mode of inheritance, whereas Maturity Onset Diabetes of the Young has a dominant mode of inheritance.
