Novel insight into the ectodermal dysplasia 11A: Splicing variant of the EDARADD gene in a family with clinical variability and literature review

J Dermatol. 2023 Oct;50(10):1357-1362. doi: 10.1111/1346-8138.16849. Epub 2023 Jun 2.


Pathogenic variants in the EDARADD gene result in autosomal recessive and autosomal dominant ectodermal dysplasia. This article reports on the fourth family in the world with ectodermal dysplasia 11A (ECTD11A) cause from a novel splicing variant in the EDARADD gene, identified by whole exome sequencing and confirmed by Sanger sequencing. The proband and his mother were heterozygous for the detected variant (NM_145861.4:c.161-2A>T). The proband manifests unusual symptoms including hyperkeratotic plaques, slow-growing hair, recurrent infection, and pectus excavatum. His mother presents hypohidrosis, extensive tooth decay, fragile nails, and sparse hair. Further studies on ECTD11A patients could be useful to characterizing the phenotype features more precisely.

Keywords: EDARADD; ECTD11A; NF-kB signaling pathway; hyperkeratotic plaque; pathogenic splicing variant.
