C-banding and AgNOR-staining were still effective complementary methods to indentify chromosomal heteromorphisms and some structural abnormalities in prenatal diagnosis

Molecular Cytogenetics, 2019
Background In prenatal diagnosis, CMA has begun to emerge as a favorable alternative to karyotype analysis, but it could not identify balanced translocations, triploidies, inversion and heteromorphisms.

Whole exome sequencing identified a novel compound heterozygous variation in COL7A1 gene causing dystrophic epidermolysis bullosa

Molecular Genetics & Genomic Medicine, 2022
Dystrophic epidermolysis bullosa (DEB) is a series of severe genetic conditions affecting skin and nails caused by mutations in the COL7A1 gene. DEB has a strong phenotypic variability.

Noninvasive prenatal diagnosis of fetal RhD status using cell-free fetal DNA in maternal plasma with TaqMan® real-time PCR assay [PDF]

, 2007
Prenatal diagnosis is now part of established obstetric practice in many countries. However, conventional methods of prenatal diagnosis of obtaining fetal tissues for genetic analysis, including amniocentesis and chorionic villus sampling, are invasive

Prenatal diagnosis of rearrangements in the fetal 22q11.2 region

Molecular Cytogenetics, 2020
Background 22q11.2 deletion syndrome (22q11.2DS) and 22q11.2 duplication syndrome (22q11.2DupS) are the most common copy number variations in humans. The clinical phenotypes of these two syndromes are variable, and there are no large sample data on the ...

Case Report: Exome Sequencing Identified a Novel Compound Heterozygous Variation in PLOD2 Causing Bruck Syndrome Type 2

Frontiers in Genetics, 2021
Bruck Syndrome (BRKS) is a rare type of recessive osteogenesis imperfecta (OI) and consists of two subtypes, BRKS1 and BRKS2, which are caused by variations in FKBP10 and PLOD2 genes, respectively.

Copy number variations associated with fetal congenital kidney malformations

Molecular Cytogenetics, 2020
Background Congenital anomalies of the kidney and urinary tract (CAKUT) constitute 20–30% of all congenital malformations. Within the CAKUT phenotypic spectrum, renal hypodysplasia (RHD) is particularly severe.
