Background and Aim: Achondroplasia is the most common skeletal dysplasia and is associated with serious complications such as foramen magnum stenosis (FMS). Current guidelines in Germany recommend polysomnography at 2-3 months and cranial imaging at 6-9 months of life in achondroplasia, whereas American Academy of Pediatrics recommends to evaluate every infant with achondroplasia for cranio-cervical junction risks via neurologic examination, polysomnography an...

Background: Primary IGF1 deficiency (PIGFD) is a rare disease defined by low IGF1 levels, GH sufficiency and absence of secondary causes of growth failure. Whereas some members of the GH–IGF axis have been shown to be implicated in the severe syndromic forms of PIGFD due to GH insensitivity, genetic causes of less severely affected patients are mostly unknown.Objective and hypotheses: The aim of the present study was to systematically investigate fr...

Background: Type 1 diabetes mellitus (T1DM) is caused by autoimmunity against the pancreatic beta-cell. Although a significant number of T1DM patients develop further autoimmune disorders during lifetime, coexisting severe immunodysregulation is rare.Objective and hypotheses: Presuming autosomal-recessive inheritance in a complex immunodysregulation disorder including T1DM in two siblings born to consanguineous parents, we performed whole exome sequencin...

Background: Primary IGF1 deficiency (PIGFD) is a rare condition defined by low IGF1 levels, GH sufficiency and absence of secondary causes of growth failure. PIGFD is an approved indication for treatment with recombinant IGF1 (rIGF1). Its genetic causes remain largely unknown.Objective and hypotheses: To elucidate genetic causes of PIGFD.Method: Clinical phenotyping followed by trio-based whole-exome sequencing (WES) in 11 complete...
