Genes affected
EDA (HGNC:3157): (ectodysplasin A) The protein encoded by this gene is a type II membrane protein that can be cleaved by furin to produce a secreted form. The encoded protein, which belongs to the tumor necrosis factor family, acts as a homotrimer and may be involved in cell-cell signaling during the development of ectodermal organs. Defects in this gene are a cause of ectodermal dysplasia, anhidrotic, which is also known as X-linked hypohidrotic ectodermal dysplasia. Several transcript variants encoding many different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 13, 2021 | This sequence change creates a premature translational stop signal (p.Trp274Cysfs*6) in the EDA gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EDA are known to be pathogenic (PMID: 9683615). For these reasons, this variant has been classified as Pathogenic. This variant has been observed in individual(s) with ectodermal dysplasia (PMID: 23687000, 25333067). ClinVar contains an entry for this variant (Variation ID: 44210). This variant is not present in population databases (ExAC no frequency). - |
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jul 22, 2011 | The Trp274CysfsX6 variant in EDA has not been reported in the literature nor pre viously identified by our laboratory. However, the Trp274CysfsX6 variant is pred icted to cause a frameshift, which alters the protein's amino acid sequence begi nning at codon 274 and leads to a premature stop codon 6 codons downstream. This alteration is then predicted to lead to a truncated or absent protein. In summa ry, this variant meets our criteria to be classified as pathogenic. - |
