Cross-species summary:
Ectodermal dysplasias are disorders that affect two or more organs of ectodermal origin, such as hair follicles, teeth, sweat glands, or nails. EDA-related ectodermal dysplasias have X-linked inheritance and affected animals present with hypo/adontia, hypotrichosis, and a lack of many eccrine glands. Altered tear composition may result in keratoconjunctivitis sicca and reduced or absent airway mucus production may predispose to chronic respiratory infections.
Phene has been renamed in OMIA from 'Anhidrotic ectodermal dysplasia, EDA-related' to 'Hypohidrotic ectodermal dysplasia, X-linked, EDA-related' [29/07/2024]
Species-specific name: scaleless
Species-specific symbol: Sca
Inheritance: co-dominant
Molecular basis: Di-Poï et al. (2026) investigated the scaleless phenotype in the bearded dragon. The authors sequenced functional candidate genes EDA and EDAR and identified an in-frame deletion of 14 amino acids (VLVDGTYFIYSQVE) in EDA as likely causal variant.

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective.
Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending
order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
