Epidermolysis bullosa simplex 5B, with muscular dystrophy

Epidermolysis bullosa simplex (EBS) is characterized by fragility of the skin (and mucosal epithelia in some instances) that results in non-scarring blisters and erosions caused by minor mechanical trauma. EBS is distinguished from other types of epidermolysis bullosa (EB) or non-EB skin fragility syndromes by the location of the blistering in relation to the dermal-epidermal junction. In EBS, blistering occurs within basal keratinocytes. The severity of blistering ranges from limited to hands and feet to widespread involvement. Additional features can include hyperkeratosis of the palms and soles (keratoderma), nail dystrophy, milia, and hyper- and/or hypopigmentation. Rare EBS subtypes have been associated with additional clinical features including pyloric atresia, muscular dystrophy, cardiomyopathy, and/or nephropathy. [from GeneReviews]

Ichthyosis, hystrix-like, with hearing loss

Hystrix-like ichthyosis with deafness (HID) syndrome is an autosomal dominant keratinizing disorder characterized by sensorineural deafness and spiky hyperkeratosis affecting the entire skin. Erythroderma appears shortly after birth. After the first year of life, spiky and cobblestone-like hyperkeratosis develops, covering the entire skin surface. Palms and soles are only mildly affected. Scarring alopecia may be present (summary by Van Geel et al., 2002). [from OMIM]

Pearson syndrome

Mitochondrial DNA (mtDNA) deletion syndromes predominantly comprise three overlapping phenotypes that are usually simplex (i.e., a single occurrence in a family), but rarely may be observed in different members of the same family or may evolve from one clinical syndrome to another in a given individual over time. The three classic phenotypes caused by mtDNA deletions are Kearns-Sayre syndrome (KSS), Pearson syndrome, and progressive external ophthalmoplegia (PEO). KSS is a progressive multisystem disorder defined by onset before age 20 years, pigmentary retinopathy, and PEO; additional features include cerebellar ataxia, impaired intellect (intellectual disability, dementia, or both), sensorineural hearing loss, ptosis, oropharyngeal and esophageal dysfunction, exercise intolerance, muscle weakness, cardiac conduction block, and endocrinopathy. Pearson syndrome is characterized by sideroblastic anemia and exocrine pancreas dysfunction and may be fatal in infancy without appropriate hematologic management. PEO is characterized by ptosis, impaired eye movements due to paralysis of the extraocular muscles (ophthalmoplegia), oropharyngeal weakness, and variably severe proximal limb weakness with exercise intolerance. Rarely, a mtDNA deletion can manifest as Leigh syndrome. [from GeneReviews]

Autoinflammation with arthritis and dyskeratosis

Autoinflammation with arthritis and dyskeratosis (AIADK) is characterized by recurrent fever, widespread skin dyskeratosis, arthritis, elevated biologic markers of inflammation, and mild autoimmunity with a high transitional B-cell level (summary by Grandemange et al., 2016). [from OMIM]
