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: 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...
