Green List (high evidence)

Over 60 pathogenic RMRP variants have been reported resulting in CHH phenotypes; multiple mouse models

Homozygous and Compound heterozygous (insertions, duplications and missense) variants have been reported resulting in loss of function.
*Founder variant g.70A>G (Amish and Finnish populations)

CHH individuals present with variable features that may include: shortened limbs, short stature, metaphysical dysplasia, fine, sparse and/or light-coloured hair, hematologic abnormalities and a spectrum of combined immunodeficiency.

Anauxetic dysplasia 1, MIM# 607095 is a more severe phenotype, whereas Metaphyseal dysplasia without hypotrichosis, MIM# 250460 is milder.
