Alström syndrome is a monogenic recessive disorder featuring an array of clinical manifestations, with systemic fibrosis and multiple organ involvement, including retinal degeneration, hearing loss, childhood obesity, diabetes mellitus, dilated cardiomyopathy (DCM), urological dysfunction, and pulmonary, hepatic, and renal failure. We evaluated a large(More)
Angelman syndrome (AS) is characterised by severe developmental delay, severe speech impairment, gait ataxia and/or limb tremor and a unique behavioural phenotype. The diagnosis of AS is based on a combination of clinical features and molecular genetic testing. Currently, molecular genetic testing (methylation analysis and UBE3A sequence analysis)(More)
Piebaldism is a rare disorder present at birth and inherited as an autosomal dominant trait. It results from a mutation in the c-kit proto-oncogene and is associated with a defect in the migration and differentiation of melanoblasts from the neural crest. Clinical manifestations and phenotypic severity strongly correlates with the site of mutation within(More)
Despite progress in understanding the molecular basis, the diagnosis of neurofibromatosis 1 (NF 1) is based on clinical criteria, established by the National Institute of Health (NIH) Consensus Conference in 1987. The association of NF1 and piebaldism has been reported, but some authors disagree with this co-occurrence. In the light of present knowledge, we(More)
We report the case of a 12-year-old girl presenting at birth with erythroderma, erosions and blisters scattered over the integument. By the age of 3 she presented generalized hyperkeratotic plaques with a cobblestone pattern and a pungent odour, most prominently around flexures, scalp and palmoplantar areas. Clinical, histological and ultrastructural(More)
Erythropoietic protoporphyria (EPP) is a rare inherited disorder of heme biosynthesis mostly caused by a deficient activity of the enzyme ferrochelatase (FECH), and consequent accumulation of protoporphyrin (PP) in various tissues. Clinical manifestations include a childhood onset, cutaneous photosensitivity and, sometimes, hepatobiliary disease. We report(More)
Hereditary pancreatitis is defined as a family history of two or more relatives with pancreatitis and clinical, biochemical, or radiologic evidence of pancreatitis. This is the fourth family described with hereditary pancreatitis related to mutation c.364C>T (p.R122C) of PRSS1 gene. The index case was a four year old child who had had his first episode of(More)
The Kallmann syndrome is characterised by the association of hypogonadotropic hypogonadism and hypo/anosmia. It represents a phenotypically and genotypically heterogeneous clinical entity, with six genes identified so far in the literature-KAL1, FGFR1, PROKR2, PROK2, CHD7 and FGF8. Mutations in the FGFR1 gene can be found in approximately 10% of the(More)
