Related Diastrophic Dysplasia in 42-Years Ukrainian Women.

Diastrophic dysplasia (DTD) is an uncommon pathology which falls under the group of skeletal dysplasias with its first symptoms observed from birth. The pathology is often featured by short stature and abnormally short extremities (also known as short-limbed dwarfism); the osseous structures of the body (bones and joints) are characterized through defective development in many body regions. More than 300 genes were reported to be involved in DTD etiology with autosomal recessive, autosomal dominant and X-linked manner.

Standards of care for CFTR variant-specific therapy (including modulators) for people with cystic fibrosis.

Cystic fibrosis (CF) has entered the era of variant-specific therapy, tailored to the genetic variants in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. CFTR modulators, the first variant-specific therapy available, have transformed the management of CF. The latest standards of care from the European CF Society (2018) did not include guidance on variant-specific therapy, as CFTR modulators were becoming established as a novel therapy.

FEATURES OF DIAGNOSIS AND ADVERSE COURSE OF NEONATAL JUVENILE XANTHOGRANULOMA: CASE REPORT.

The work describes a case of rare neonatal systemic juvenile xanthogranuloma with an initial damage of the scalp, limbs, back and abdomen, multiple damages of the parenchyma of both lungs, spleen and liver with the development of a severe form of congenital cholestatic hepatitis. The diagnosis was established on the basis of histopathological and immunohistochemical examination of the skin nodules. The child on the background of therapy under the Langerhans cell histiocytosis III program achieved a partial response, which was manifested by a reduction of granulomatous formations on the skin, elimination of liver failure, but retained hepatosplenomegaly, specific lesions of the lung parenchyma, liver, and left kidney.

Genetic data protection as an indispensable element of genomic medicine development.

The immense progress in molecular biology observed in the last decades has led to a fundamental change in our understanding of the etiology of human diseases. Whole genome analyses, both DNA sequencing and microarray comparative genomic hybridization, allowed for identification of previously unknown diseases and syndromes. Therefore, in difficult‑to‑diagnose cases, clinical diagnosis is being replaced by molecular diagnosis (molecular dysmorphology, genomic medicine).
