摘要

Chromosome 14q32.3 deletions are uncommon, with most described patients harboring a ring chromosome 14. Only 15 deletions have been described not associated with ring formation or other complex chromosomal rearrangements. Here, we describe a child with the smallest deletion of chromosome 14q32.3 reported in the literature. This child's deletion encompasses at most 0.305Mb and six genes including NUDT14, BRF1, BTBD6, PACS2, MTA1, and TEX22. He has similar clinical findings, including mild facial dysmorphisms and intellectual disability, as other individuals with much larger deletions of the terminus of the long arm of chromosome 14. This suggests that the genes deleted in our patient contribute to the 14q32 deletion syndrome.
