For example, short stature caused by postnatal growth insufficiency was reported in affected individuals from a multigenerational kindred with hypocalcemia and a germline heterozygous gain‐of‐function mutation, Arg60Leu,7 and it is possible that the occurrence of mild bilateral cataracts in the proband (individual I.4) may also be due to the germline gain‐of‐function Gα11 mutation, Val340Met. This evidence concerns the gene GNA11 and Hypocalcemia.
