[Preclinical diagnostics of von Hippel-Lindau syndrome in a child].

The description of the child aged 5 months with the von Hippel-Lindau syndrome without any manifestations of this syndrome is presented. The reason for the molecular genetic examination was the presence of cases of this syndrome in the family (mother and sister). The heterozygous variant c.

[Primary Generalized Glucocorticoid Resistance: a case report].

Primary glucocorticoid resistance (OMIM 615962) is a rare endocrinologic condition caused by resistance of the human glucocorticoid receptor (hGR) to glucocorticoids (GR) and characterised by general or partial insensitivity of target organs to GK. Compensatory activation of hypothalamic-pituitary-andrenal axis results in development of a various pathological conditions caused by overstimulation of adrenal glands. Clinical spectrum may range from asymptomatic cases to severe cases of mineralocorticoid and/or androgen excess.

[Characterization of new splicing mutation in steroid 21-hydroxylase gene].

Novel mutation in CYP21A2 gene causing the steroid 21-hydroxylase deficiency - C to G substitution in 7-position ofintron 2 acceptor splice site (c.290-7C>G) was identified. The effect of the mutation on splicing was checked in the system of CYP21A minigene expression in the cultured mammalian cells.
