A rare multiple congenital anomalies/dysmorphic syndrome characterized by a variable combination of dental, cutaneous, ocular, and bone abnormalities, including pyramidal and fused molar roots, taurodontism, an abnormal upper lip without a cupid's bow and thickened and wide philtrum, juvenile glaucoma, syndactyly, and clinodactyly. There have been no further descriptions in the literature since 1973. Is a True Hereditary disorder of the integument Inferred relationship Some
A rare syndromic agammaglobulinaemia characterised by profound B-cell depletion (with normal T-cell numbers) resulting in agammaglobulinaemia, associated with severe developmental delay, microcephaly, craniosynostosis, cleft palate, narrowing of the choanae, blepharophimosis, and severe dermatitis. Additional reported features include distal joint contractures, renal/genitourinary anomalies, and mild cerebral atrophy, among others. Is a True Hereditary disorder of the integument Inferred relationship Some
A form of localized dystrophic epidermolysis bullosa characterized by dystrophic nails in the absence of blistering. The nail deformity is often limited to toenails which can appear thickened and shortened, or may be absent. No other cutaneous or extracutaneous symptoms are observed. Is a False Hereditary disorder of the integument Inferred relationship Some
LOC syndrome is a subtype of junctional epidermolysis bullosa characterized by an altered cry in the neonatal period and by aberrant production of granulation tissue in particular affecting the upper airway tract, conjunctiva and periungual/subungual sites. Is a False Hereditary disorder of the integument Inferred relationship Some
Palmoplantar keratoderma-XX sex reversal-predisposition to squamous cell carcinoma syndrome is characterised by sex reversal in males with a 46, XX (SRY-negative) karyotype, palmoplantar hyperkeratosis and a predisposition to squamous cell carcinoma. To date, five cases (four of whom were brothers) have been described. The aetiology is unknown. Is a False Hereditary disorder of the integument Inferred relationship Some
Palmoplantar keratoderma-deafness syndrome is a keratinization disorder characterized by focal or diffuse palmoplantar keratoderma. A patchy distribution is observed with accentuation on the thenars, hypothenars and the arches of the feet. The disease becomes apparent in infancy and is associated with sensorineural hearing loss that shows a variable age of onset. Due to genetic and clinical similarities, it has been proposed that palmoplantar keratoderma-deafness syndrome, knuckle pads-leukonychia-sensorineural deafness-palmoplantar hyperkeratosis syndrome and keratoderma hereditarium mutilans may represent variants of one broad disorder of syndromic deafness with heterogeneous phenotype. The disease is transmitted in an autosomal dominant manner with incomplete penetrance. Is a False Hereditary disorder of the integument Inferred relationship Some
A rare autosomal recessive, isolated diffuse palmoplantar keratoderma characterized by transgressive and nonprogressive palmoplantar keratoderma resembling a mild form of mal de Meleda. Is a False Hereditary disorder of the integument Inferred relationship Some
A rare X-linked syndromic intellectual disability characterized by intellectual impairment of variable severity, progressive lower limb spasticity, and diffuse palmoplantar hyperkeratosis. Additional manifestations include pes cavus, extensor plantar responses, hand tremor, and mild dysmorphic facial features. Is a False Hereditary disorder of the integument Inferred relationship Some
Hypohidrosis due to genetic abnormality of eccrine gland structure and function (disorder) Is a True Hereditary disorder of the integument Inferred relationship Some
