FAMILIAL CASE OF CHROMOSOME 22q11.2 DELETION SYNDROME

The work represents a family which includes two siblings with chromosome 22q11.2 deletion syndrome. Their mother carries the same chromosome anomaly, but with apparently normal phenotype. Hence, this interesting case of 22q11.2 deletion syndrome exists in 2 generations of the same family. The aim of...

Description
Summary:The work represents a family which includes two siblings with chromosome 22q11.2 deletion syndrome. Their mother carries the same chromosome anomaly, but with apparently normal phenotype. Hence, this interesting case of 22q11.2 deletion syndrome exists in 2 generations of the same family. The aim of this study was analysis of phenotypic manifestations in the family members with 22q11.2 deletion syndrome. Clinical examination of the patients, their life story and pedigree and, along with routine clinical and biochemical analysis, and immune state testing, along with ultrasound imaging of thymus and thyroid glands, heart and abdominal cavity. We made conclusions that the phenotypic features associated with chromosome 22q11.2 deletion may be different for distinct family members. Further studies are required to determine length of deleted segment and the genes affected, as well as to establish the genotype-phenotype interactions and disease prognosis.
