High frequency of CHD7 mutations in congenital hypogonadotropic hypogonadism
Gonçalves, CI; Patriarca, FM; Aragüés, JM; Carvalho, D; Fonseca, F; Martins, S; Marques, O; Pereira, BD; Martinez-de-Oliveira, J; Lemos, MCCongenital hypogonadotropic hypogonadism (CHH) is characterized by lack of normal pubertal development due to deficient gonadotropin-releasing hormone (GnRH) secretion or action, and is caused by genetic defects in several genes. Mutations in the CHD7 gene cause CHARGE syndrome (Coloboma of the eye, Heart defects, Atresia of the choanae, Retardation of growth and development, Genital hypoplasia and Ear abnormal...

Expanding the Genetic Spectrum of ANOS1 Mutations in Patients with Congenital H...
Gonçalves, CI; Fonseca, F; Borges, T; Cunha, F; Lemos, MCSTUDY QUESTION: What is the prevalence and functional consequence of ANOS1 (KAL1) mutations in a group of men with congenital hypogonadotropic hypogonadism (CHH)? SUMMARY ANSWER: Three of forty-two (7.1%) patients presented ANOS1 mutations, including a novel splice site mutation leading to exon skipping and a novel contiguous gene deletion associated with ichthyosis. WHAT IS KNOWN ALREADY: CHH is characterized ...
