Background: Self-limited delayed puberty (DP) often segregates in an autosomal dominant pattern, suggesting that inheritance is conferred by a small number of genes. However, the underlying genetic background is mostly unknown. By comparison, many genes have been identified where loss-of-function mutations lead to hypogonadotropic hypogonadism (HH). Despite likely overlap between the pathophysiology of delayed puberty and conditions of GnRH deficiency, few studies have examine...

Background: Self-limited DP often segregates in an autosomal dominant pattern, but in the majority of patients the neuroendocrine pathophysiology and its genetic regulation remain unclear. By comparison, many genes have been identified where loss-of-function mutations lead to IHH. Despite likely overlap between the pathophysiology of DP and conditions of GnRH deficiency, few studies have examined the contribution of mutations in IHH genes to the phenotype of DP.<p class="a...

Background: Abnormal pubertal timing affects over 4% of adolescents and is associated with adverse health and psychosocial outcomes. Previous studies estimate that 60–80% of variation in the timing of pubertal onset is genetically determined. However, despite this strong heritability, little is known about the genetic control of human puberty. Self-limited delayed puberty (DP) segregates in an autosomal dominant pattern, but in the majority of patients the neuroendocrine ...

Background: Timing of puberty is associated with height, cardiovascular health and cancer risk, with a significant public health impact. Previous studies estimate that 60–80% of variation in the timing of pubertal onset is genetically determined. Self-limited delayed puberty (DP) segregates in an autosomal dominant pattern, but the underlying genetic background is unknown.Methods: We performed whole exome sequencing in 111 members of 18 families fro...
