Small supernumerary marker chromosomes derived from human chromosome 11 [PDF]

open access: yesFrontiers in Genetics, 2023
Introduction: With only 39 reported cases in the literature, carriers of a small supernumerary marker chromosome (sSMC) derived from chromosome 11 represent an extremely rare cytogenomic condition.Methods: Herein, we present a review of reported sSMC(11),

Paternal Transmission of Small Supernumerary Marker Chromosome 15 Identified in Prenatal Diagnosis Due to Advanced Maternal Age [PDF]

open access: yesClinical Medicine Insights: Case Reports, 2015
The detection of supernumerary marker chromosomes (SMCs) in prenatal diagnosis is always a challenge. In this study, we report a paternally inherited case of a small SMC(15) that was identified in prenatal diagnosis due to advanced maternal age.

Unexpected results in the constitution of small supernumerary marker chromosomes [PDF]

open access: yesEuropean Journal of Medical Genetics, 2012
Traditional approaches for the classification of Small Supernumerary Marker Chromosomes (sSMC), mostly based on FISH techniques, are time-consuming and not always sufficient to fully understand the true complexity of this class of rearrangements.

Another Small Supernumerary Marker Chromosome Derived from Chromosome 9 in a Klinefelter Patient

open access: yesWest Indian Medical Journal, 2012
Marker chromosomes are very rare in Klinefelter patients and phenotypic findings are related to the affected chromosomal region. The phenotypic effects of small supernumerary marker chromosomes (sSMC) range from multiple malformations/mental retardation to no effect (ie a normal phenotype).

Small supernumerary marker chromosomes: A legacy of trisomy rescue? [PDF]

open access: yesHuman Mutation, 2018
We studied by a whole genomic approach and trios genotyping, 12 de novo, nonrecurrent small supernumerary marker chromosomes (sSMC), detected as mosaics during pre- or postnatal diagnosis and associated with increased maternal age. Four sSMCs contained pericentromeric portions only, whereas eight had additional non-contiguous portions of the same ...

Prenatal Diagnosis and Molecular Cytogenetic Characterization of a Small Supernumerary Marker Chromosome Derived from Chromosome 18 and Associated With a Reciprocal Translocation Involving Chromosomes 17 And 18

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2010
Objective: Prenatal diagnosis of small supernumerary marker chromosomes (sSMC) gives rise to difficulties in genetic counseling, and requires molecular cytogenetic technologies such as spectral karyotyping, fluorescence in situ hybridization, multicolor ...

Supernumerary Marker Chromosome Identified in Asian Elephant (Elephas maximus)

open access: yesAnimals, 2023
We identified a small, supernumerary marker chromosome (sSMC) in two phenotypically normal Asian elephants (Elephas maximus): a female (2n = 57,XX,+mar) and her male offspring (2n = 57,XY,+mar). sSMCs are defined as structurally abnormal chromosomes that

A new small supernumerary marker chromosome, generating mosaic pure trisomy 16q11.1–q12.1 in a healthy man [PDF]

open access: yesMolecular Cytogenetics, 2008
Here we report on a healthy and fertile 30 years old man, who was carrier of a small supernumerary marker chromosome (sSMC). The application of molecular techniques such as fluorescence in situ hybridisation (FISH), microdissection and reverse painting ...

Molecular and cytogenetic analysis of small supernumerary marker chromosomes in prenatal diagnosis

open access: yesMolecular Cytogenetics, 2023
Background Small supernumerary marker chromosome (sSMC) is a structurally abnormal chromosome of unknown origin by conventional cytogenetics. The understanding of clinical significance of sSMC is still limited in prenatal diagnosis.
