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.

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),

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 ...

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 ...

A case of isodicentric chromosome 15 presented with epilepsy and developmental delay [PDF]

open access: yesKorean Journal of Pediatrics, 2012
We report a case of isodicentric chromosome 15 (idic(15) chromosome), the presence of which resulted in uncontrolled seizures, including epileptic spasms, tonic seizures, and global developmental delay.

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

open access: yes, 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.

Case Report: How whole-genome sequencing-based cell-free DNA prenatal testing can help identify a marker mhromosome

open access: yesFrontiers in Genetics, 2022
A supernumerary marker chromosome (SMC) is a structurally abnormal chromosome that cannot be characterized by conventional banding cytogenetics. Marker chromosomes are present in 0.075% of prenatal cases.

Identification of satellited markers by microdissection and fluorescence in situ hybridization: a clinical case of isodicentric chromosome 22

open access: yesEgyptian Journal of Medical Human Genetics, 2021
Background The presence of small supernumerary marker chromosomes (sSMCs) in a karyotype leads to diagnostic questions because the resulting extra material may cause abnormal development depending on the origin of the duplication/triplication.

Prenatal diagnosis and molecular cytogenetic characterization of a small supernumerary marker chromosome derived from chromosome 15 in a pregnancy associated with recurrent Down syndrome

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2021
Objective: We present prenatal diagnosis and molecular cytogenetic characterization of a small supernumerary marker chromosome (sSMC) derived from chromosome 15 in a pregnancy associated with recurrent Down syndrome. Case report: A 33-year-old, gravida 4,
