Abstract |
Whole genome profiling such as array comparative genomic hybridization has identified novel genomic imbalances. Copy number studies led to an explosion of the discoveries of new segmental duplication-mediated deletions and duplications. These rearrangements are mostly the result of non-allelic homologous recombination (NAHR) between low-copy repeats or segmental duplications. We have identified an individual with a small, rare deletion on chromosome 2q21.1 with psychomotor delay, hyperactivity, and aggressive behavior. The rearranged region is flanked by large complex low-copy repeats and includes only five genes: GPR148, FAM123C (AMER3), ARHGEF4, FAM168B, and PLEKHB2. The comparison between our patient and the cases previously reported in the literature contributes to a better definition of genotype-phenotype correlation of 2q21.1 microdeletions. |
