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. [provided by RefSeq, Jul 2008]
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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 11 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 3 benign, 5 uncertain in NM_022336.4
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 34 curated pathogenic missense variants (we use a threshold of 10). The gene has 8 curated benign missense variants. Gene score misZ: 0.72828 (below the threshold of 3.09). Trascript score misZ: 1.2871 (below the threshold of 3.09). GenCC associations: The gene is linked to ectodermal dysplasia 10B, hypohidrotic/hair/tooth type, autosomal recessive, ectodermal dysplasia 10A, hypohidrotic/hair/nail type, autosomal dominant, autosomal dominant hypohidrotic ectodermal dysplasia, autosomal recessive hypohidrotic ectodermal dysplasia.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.955
PP5
Variant 2-108897130-C-T is Pathogenic according to our data. Variant chr2-108897130-C-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 5855.Status of the report is criteria_provided_single_submitter, 1 stars.
