Genes affected

EDAR (HGNC:2895): (ectodysplasin A receptor) This gene encodes a member of the tumor necrosis factor receptor family. The encoded transmembrane protein is a receptor for the soluble ligand ectodysplasin A, and can activate the nuclear factor-kappaB, JNK, and caspase-independent cell death pathways. It is required for the development of hair, teeth, and other ectodermal derivatives. Mutations in this gene result in autosomal dominant and recessive forms of hypohidrotic ectodermal dysplasia.

EDAR links:

RANBP2 (HGNC:9848): (RAN binding protein 2) RAN is a small GTP-binding protein of the RAS superfamily that is associated with the nuclear membrane and is thought to control a variety of cellular functions through its interactions with other proteins. This gene encodes a very large RAN-binding protein that immunolocalizes to the nuclear pore complex. The protein is a giant scaffold and mosaic cyclophilin-related nucleoporin implicated in the Ran-GTPase cycle. The encoded protein directly interacts with the E2 enzyme UBC9 and strongly enhances SUMO1 transfer from UBC9 to the SUMO1 target SP100. These findings place sumoylation at the cytoplasmic filaments of the nuclear pore complex and suggest that, for some substrates, modification and nuclear import are linked events. This gene is partially duplicated in a gene cluster that lies in a hot spot for recombination on chromosome 2q. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Arg358*) in the EDAR gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 91 amino acid(s) of the EDAR protein. This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with hypohidrotic ectodermal dysplasia (PMID: 10431241, 17125505, 24884697, 26336973, 27305980). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 5852). For these reasons, this variant has been classified as Pathogenic. -
