A fetus with de novo 2q33.2q35 deletion including MAP2 with brain anomalies, esophageal atresia, and laryngeal stenosis
American Journal of Medical Genetics. Part A , Volume 164 - Issue 1 p. 194- 198
Deletions of the long arm of chromosome 2 are rare. Few cases of interstitial deletions of the 2q33q35 region have been reported. Individuals with deletions in this region have growth retardation, psychomotor retardation, micrognathia, microcephaly, and apparently low-set ears. We describe a female fetus with a de novo deletion of 2q33.2 to q35 with delayed gyral formation with widespread neuronal heterotopia of the white matter, small cerebellum, esophageal atresia, laryngeal stenosis, micrognathia, and intrauterine growth retardation. With the use of karyotyping and high-resolution array comparative genomic hybridization the boundaries and gene content of the deletion were identified. Our aim was to determine whether a candidate gene for the brain phenotype was present in the deletion. By this means and based on literature we pinpointed the microtubule associated gene MAP2 as a candidate for the brain anomalies.
