PG - 24-31 LID - 10.1159/000532051 [doi] AB - Intrachromosomal insertions are complex structural rearrangements that are challenging to interpret using classical cytogenetic methods. We report a male patient carrying a recombinant X chromosome derived from a maternally inherited intrachromosomal insertion. The patient exhibited developmental delay, intellectual disability, behavioral disorder, and dysmorphic facial features. To accurately identify the rearrangements in the abnormal X chromosome, additional cytogenetic studies were conducted, including fluorescence in situ hybridization (FISH), multicolor-banding FISH, and array comparative genomic hybridization. The results showed a recombinant X chromosome, resulting in a 13.05 Mb interstitial duplication of segment Xp22.33-Xp22.13, which was inserted at cytoband Xq26.1. The duplicated region encompasses 99 genes, some of which are associated with the patient's clinical manifestations. We propose that the combined effects of the Xp-duplicated genes may contribute to the patient's phenotype. CI - (c) 2023 S. Karger AG, Basel.
