Summary
This region is known to undergo non-allelic homologous recombination (NAHR) with another region, the LCR2q21.1 distal recombination region, found about 606 kb centromere-distal to this region, in direct orientation relative to this region. Both this region and the LCR2q21.1 distal recombination region are found within 109 kb low-copy repeat regions that share high DNA sequence identity. NAHR between the two regions can result in deletions and duplications of the intervening sequence. Multiple genes are found in the intervening sequence, including the Rho guanine nucleotide exchange factor 4 (ARHGEF4) and G protein-coupled receptor 148 (GPR148) genes. Phenotypic consequences of the deletion may include developmental delays, attention-deficit hyperactivity disorder (ADHD), epilepsy or electroencephalogram (EEG) abnormalities and behavioral problems. A recombination breakpoint of an individual with the genomic rearrangement is indicated as an NAHR sub-region on the record. [provided by RefSeq, Jun 2016]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
