Epidermolysis bullosa and congenital skin fragility
Gene: NAXD
After consulting the clinical team at Genomics England, this gene has been added to this panel with an Amber rating (pending more evidence) as there is a skin phenotype is present in patients and may be the first things the patient is being seen for (PMID: 33224489).Created: 19 Jul 2021, 9:13 a.m. | Last Modified: 19 Jul 2021, 9:13 a.m.
Panel Version: 1.49
Affected individuals show normal early development followed by acute psychomotor regression with ataxia, hypotonia, and sometimes seizures triggered by acute fever. The affected infants usually die in the first few years of life. Brain imaging shows multiple abnormalities, including brain edema and white matter abnormalities. The infants also present with skin lesions/rash.Created: 9 Jun 2021, 11:05 a.m. | Last Modified: 9 Jun 2021, 11:05 a.m.
