First Report of a Small Supernumerary der(8;14) Marker Chromosome
Cytogenetic and Genome Research, 2013 Small supernumerary marker chromosomes (sSMC) are structurally abnormal chromosomes, generally equal in size or smaller than a chromosome 20 of the same metaphase spread. Most of them are unexpectedly detected in routine karyotype analyses, and it is usually not easy to correlate them with a specific clinical picture.

Molecular cytogenetic identification of small supernumerary marker chromosomes using chromosome microarray analysis [PDF]
Molecular Cytogenetics, 2019 Background This study aimed to evaluate the feasibility of chromosomal microarray analysis (CMA) in detecting the origin and structure of small supernumerary marker chromosomes (sSMCs) in prenatal and postnatal cases and to clarify sSMC-related genotype ...

Complex small supernumerary marker chromosomes – an update [PDF]
Molecular Cytogenetics, 2013 Complex small supernumerary marker chromosomes (sSMC) constitute one of the smallest subgroups of sSMC in general. Complex sSMC consist of chromosomal material derived from more than one chromosome; the best known representative of this group is the derivative chromosome 22 {der(22)t(11;22)} or Emanuel syndrome.

Small Supernumerary Marker Chromosomes in Human Infertility [PDF]
Cytogenetic and Genome Research, 2015 Small supernumerary marker chromosomes (sSMC) are structurally abnormal chromosomes that cannot be unambiguously identified by banding cytogenetics. The objective of this study was to provide an overview of sSMC frequency and characterization in a context of infertility and to review the literature describing sSMC in relation with male and female ...

Somatic Mosaicism in Cases with Small Supernumerary Marker Chromosomes [PDF]
Current Genomics, 2010 Somatic mosaicism is something that is observed in everyday lives of cytogeneticists. Chromosome instability is one of the leading causes of large-scale genome variation analyzable since the correct human chromosome number was established in 1956.
