Abstract
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. We describe clinical case of a 42-year-old woman from the west of Ukraine with diastrophic dysplasia and two pathogenic variants c.1020_1022del (p.Val341del) and c.1957T>A (p.Cys653Ser) identified in SLC26A2 gene. SLC26A2-related diastrophic dysplasia was confirmed based on the presence of pathogenic variants in SLC26A2, which is associated with autosomal recessive forms of skeletal dysplasia, combined with phenotypic symptoms and radiographic findings.
