{Reference Type}: Case Reports {Title}: Detection of 4p16.3 deletion and 11p15.5p15.4 gain in a boy by comparative genomic hybridization array: A case report. {Author}: Kaya I; {Journal}: World J Clin Cases {Volume}: 12 {Issue}: 8 {Year}: 2024 Mar 16 {Factor}: 1.534 {DOI}: 10.12998/wjcc.v12.i8.1517 {Abstract}: BACKGROUND: Nonallelic homologous recombination (NAHR) of segmental duplications or low copy repeats (LCRs) result in DNA gain/loss and play an important role in the origin of genomic disorders.
METHODS: A 3-year- old boy was referred for genetic analysis. Comparative genomic hybridization array analysis revealed a loss of 3776 kb in the 4p16.3 chromosomal region and a gain of 3201 kb in the 11p15.5p15.4 chromosomal region.
CONCLUSIONS: Genomic imbalances caused by NAHR in LCRs result in deletion and duplication syndromes.
