Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PM2PP5_Moderate
The NM_001399.5(EDA):c.132_135dup(p.Phe46GlyfsTer55) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. L44L) has been classified as Benign. Variant results in nonsense mediated mRNA decay.

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:1
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Apr 08, 2014 | The Phe46fs variant in EDA has not been previously reported in individuals with hypohidrotic ectodermal dysplasia and was absent from large population studies. This frameshift variant is predicted to alter the protein?s amino acid sequence beginning at position 46 and lead to a premature termination codon 55 amino aci ds downstream. This alteration is then predicted to lead to a truncated or absen t protein. Loss of function of function of the EDA gene is an established diseas e mechanism in XLHED. In summary, this variant meets our criteria to be classifi ed as pathogenic (http://pcpgm.partners.org/LMM). - |
