There are several cases in OMIM reported with Hypogonadotropic hypogonadism 2 with or without anosmia that also have hearing impairment. In Gene2Phenotype, Kallman syndrome Type 2 has Sensorineural hearing impairment as a HPO term. This gene is Green on the Idiopathic hypogonadotropic hypogonadism gene panel Version 1.14, should it also be green on the Congenital hearing impairment panel?
