Green List (high evidence)

Comment on list classification: There are two unrelated cases and some functional evidence available in support of the association of this gene to hypogonadotropic hypogonadism. Hence, this gene can be rated green on the next GMS update.

Panel Version: 3.20
PMID:25192046 reported the identification of two different homozygous variants (c.832C>T/ p.His278Tyr and c.2270C>T/ p.Arg724Ter) in two unrelated Kurdish families with Kallmann syndrome. In addition, there is functional evidence for c.832C>T variant.

This gene has been associated with relevant phenotypes in OMIM (MIM #616030) and Gene2Phenotype (with 'strong' rating on the DD panel)
