The last two molecular diagnostic steps have not been performed because TNXB-related classical-like EDS (TNXB-clEDS), the ultrarare type of EDS due to biallelic null variants in TNXB, has been excluded by the proband's physical examination that revealed the presence of atrophic scarring. The gene discussed is TNXB; the disease is Ehlers-Danlos syndrome.
