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]

Pathogenic:3

Likely pathogenic, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 28, 2017	The EDAR c.719_722delAAGA (p.Lys240ArgfsTer7) variant has been reported in two studies and is found in a homozygous state in four patients from two consanguineous families with hypohidrotic ectodermal dysplasia (Naeem et al. 2005; Bashyam et al. 2012). Three of these patients were from the same family (Naeem et al. 2005). The p.Lys240ArgfsTer7 variant was also present in five unaffected heterozygous carriers, two from one family and three from the other including both parents and one sister. Control data are unavailable for this variant and it is not found in the 1000 Genomes Project, the Exome Sequencing Project, or the Exome Aggregation Consortium. The p.Lys240ArgfsTer7 variant has not been reported in association with autosomal dominant HED. Based on the evidence and due to the potential impact of frameshift variants, the p.Lys240ArgfsTer7 variant is classified as likely pathogenic for autosomal recessive hypohidrotic ectodermal dysplasia. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -
Pathogenic, criteria provided, single submitter	clinical testing	3billion	Jan 03, 2022	Frameshift: predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant (PVS1_VS). The variant has been reported at least twice as pathogenic/likely pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000005859, PMID:16029325).It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000004, PM2_M). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -
