Genetic and clinical heterogenicity in Russian adolescents with congenital isolated hypogonadotropic hypogonadism

Kokoreva Kristina , Chugunov Igor , Volevodz Natalia , Bezlepkina Olga , Peterkova Valentina

Background: Congenital isolated hypogonadotropic hypogonadism (СIHH) is a clinically and genetically heterogenous disorder characterized by absence or abnormal gonadotropin-releasing hormone secretion (GnRH). Adolescents with CIHH have complete or partial pubertal failure. Pathogenic variants in more than 60 genes have been associated with CIHH. CIHH can be complete, partial or reversal. Boys with CIHH may have micropenis and cryptorchidism. Except reprodu...

Clinical case of rare association of Treacher Collins syndrome with micropenis and unilateral cryptorchidism in Russian patient

Kokoreva Kristina , Pisareva Elena , Zyuzikova Zinaida , Volevodz Natalia , Peterkova Valentina

Objective: Treacher Collins syndrome (TCS) is rare autosomal dominant genetic condition characterized by the following features of the head and face: absence of the ears, down-slanting palpebral fissures, eyelid colobomas, microtia, bilateral choanal atresia and etc. Prevalence of TCS is from 1 per 25,000 to 1 in 50,000 live births. Most of TCS patients don’t have endocrine disorders that is why endocrinologists are not familiar with this condit...

Congenital hypogonadotropic hypogonadism associated with X-linked ichthyosis due to X-chromosome microdeletion identified by chromosomal microarray

Kokoreva Kristina , Chugunov Igor , Kalinchenko Natalia , Latyshev Oleg , Samsonova Lyubov , Bezlepkina Olga ,

Objective: to assess diagnostic usefulness and accuracy of different tools in patients with Kallmann syndrome and ichthyosis due to X-chromosome microdeletion.Materials: &scy;ongenital hypogonadotropic hypogonadism due to KAL1 pathological variants manifest with micropenis, cryptorchidism, delay of puberty, and not associated with disorder of sex development. This condition can be associated with ichthyosis due to deletion of X chromosome region with genes KAL...
