Green List (high evidence)

Heterozygous TRPM7 variants are associated with hypomagnesaemia with secondary hypocalcaemia (HSH)(PMID: 39099563; 35712613; 35561741). Six TRPM7 variants have been identified in six unrelated cases of HSH, one of the variants was found in three members of one family. The remaining variants were de novo. In addition to HSH, other phenotypic feature have been seen in those carrying TRPM7 variants, including seizures (4/6), motor skill defects (5/6), autism spectrum disorder (4/6) (PMID: 39099563; 35712613; 35561741). Functional studies suggest a loss of function effect of the TRPM7 variants (PMID: 39099563; 35561741).
