Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_001399.5(EDA):c.991C>T(p.Gln331Ter) variant causes a stop gained change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Q331Q) has been classified as Likely benign.

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]

Hypohidrotic X-linked ectodermal dysplasia Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | May 05, 2014 | The Gln331X variant in EDA has been previously reported in one individual with X -linked hypohidrotic ectodermal dysplasia (XLHED; Dietz 2013). The Gln331X nonse nse variant leads to a premature termination codon at position 331, which is pre dicted to lead to a truncated or absent protein. Loss of function of the EDA gen e is an established disease mechanism in XLHED. In summary, this variant meets o ur criteria to be classified as pathogenic (http://pcpgm.partners.org/LMM). - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 12, 2022 | ClinVar contains an entry for this variant (Variation ID: 163324). For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the EDA protein in which other variant(s) (p.Ala367Valfs*10) have been determined to be pathogenic (Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This premature translational stop signal has been observed in individual(s) with ectodermal dysplasia (PMID: 23553579). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln331*) in the EDA gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 61 amino acid(s) of the EDA protein. - |
