Baller-Gerold syndrome

What is Baller-Gerold syndrome?

Baller-Gerold syndrome is a rare condition characterized by the premature fusion of certain skull bones (craniosynostosis) and abnormalities of bones in the arms and hands, sometimes referred to as radial ray anomalies. Many cases of Baller-Gerold syndrome are caused by mutations in the RECQL4 gene. These cases are inherited in an autosomal recessive manner. In a few reported cases, the characteristic features of Baller-Gerold syndrome have been associated with prenatal exposure to a drug called sodium valproate which is used to treat epilepsy and certain psychiatric disorders. Treatment may include surgery for treatment of craniosynostosis or reconstruction of the index finger to functional thumb. The symptoms of Baller-Gerold syndrome overlap with features of Rothmund-Thomson syndrome and RAPADILINO syndrome which are also caused by the RECQL4 gene. Researchers are trying to determine if these conditions are separate disorders or part of a single syndrome with overlapping signs and symptoms.

Can Baller-Gerold syndrome be detected before birth?

Serial ultrasound examination may identify limb shortening, radial hypo/aplasia and abnormal head shape (brachycephaly). Ultrasound examination may reveal these findings as early as 14 weeks' gestation in fetuses at-risk for this condition.[3513

Prenatal diagnosis for pregnancies at increased risk for Baller-Gerold syndrome is possible by analysis of DNA extracted from fetal cells obtained by amniocentesis usually performed at approximately 15 to 18 weeks' gestation or chorionic villus sampling (CVS) at approximately ten to 12 weeks' gestation. Both disease-causing alleles must be identified before prenatal testing can be performed.
