Spondyloocular syndrome (OMIM 605822) is an autosomal recessive disorder characterized by skeletal complaints (osteoporosis, platyspondyly, multiple bone fractures), hearing loss and ocular symptoms (cataracts, retinal detachment). XYLT2 gene (OMIM 608125) mutation encoding xylosyltransferase II enzyme which is responsible from the first step of proteoglycan assembly is responsible for the pathogenesis. Phenotypical variability is associated with varying genetic expre...

Introduction: Costello syndrome is a rare RASopathy that is associated with such characteristics as prenatal overgrowth, postnatal growth retardation, mental-motor retardation, coarse face appearance, loose skin on the neck, hands and feet, cardiovascular abnormalities, deep palmar and plantar lines and a predisposition to various types of cancer. Several endocrine disorders, including growth hormone deficiency, adrenal failure, glucose intolerance, hyperprolactinemia and hypo...

Background: Triple A syndrome is a rare autosomal recessive disorder characterized by adrenal failure, alacrima, achalasia, and a variety of neurological features. In 70% of the families it is caused by mutations in the AAAS gene. Linkage analyses indicated genetic heterogeneity and exome sequencing revealed two further genes causing triple A-like syndromes.Objective and hypotheses: To summarise the genotypes and phenotypes of classic triple A s...
