Chromosome 17 trisomy [Supplementary Concept]

Duplication of chromosome 17 in some tissues (trisomy 17 mosaicism) is among the rarest trisomy in humans and full trisomy 17 has never been observed in living individuals. In mosaic cases, where trisomy occurs only in some cell populations, affected individuals may experience developmental delays, body asymmetry, slow growth, and cerebellar hypoplasia.

Chromosome 8, mosaic trisomy [Supplementary Concept]

A chromosomal disorder characterized by the presence of a third copy of chromosome 8 in some cell populations. Affected individuals may have craniofacial abnormalities, mild intellectual disability, joint, urinary, cardiac, and skeletal defects. They are also at higher risk for developing WILMS TUMOR and MYELODYSPLASTIC SYNDROMES.

Mosaic variegated aneuploidy syndrome [Supplementary Concept]

A hereditary autosomal recessive disorder characterized by mosaicism, with ANEUPLOIDIES, particularly TRISOMIES and MONOSOMIES of different CHROMOSOMES occuring in the cells of various tissues; aneuploid cells usually constitute more than 25%. Affected individuals typically have severe intrauterine growth retardation and MICROCEPHALY. Various other CONGENITAL ABNORMALITIES and DEVELOPMENTAL DISABILITIES may also be present, as well as an increased risk for developing CANCER. Germline mutations in the BUB1B gene have been identified. OMIM: 257300
