We report a 15-day-old girl with partial trisomy 4q syndrome who presented with neonatal cholestasis. She had dysmorphic facial features and preaxial polysyndactyly of the right hand. The other findings were generalized hypertrichosis, pes equinovarus, oedema on feet and mild hepatomegaly. No specific reason for the cholestasis with elevated liver enzymes and direct bilirubinemia were characterized. Cytogenetic analyses revealed a karyotype 46,XX,der(13)t(4;13)(q25;p13). This is the first patient with partial trisomy 4q syndrome presented with neonatal cholestasis.

Department of Laboratory, The Second People's Hospital of Yibin City, Yibin, Sichuan, China.
Objective: This study aims to assess the diagnostic efficacy of a combined approach integrating chromosomal karyotyping, copy number variation sequencing (CNV-seq), and quantitative fluorescence polymerase chain reaction (QF-PCR) in detecting chromosomal abnormalities in high-risk pregnancies.
Methods: This retrospective study analyzed 617 high-risk pregnancies undergoing prenatal diagnosis from February 2023 to August 2024, with amniotic fluid samples concurrently analyzed using karyotyping, CNV-seq, and QF-PCR. We evaluated clinical characteristics, diagnostic yields, and inter-method concordance rates.

Approximately one in every 800 children is born with the severe aneuploid condition of Down Syndrome, a trisomy of chromosome 21. Low blood pressure (hypotension) is a common condition associated with DS and can have a significant impact on exercise tolerance and quality of life. Little is known about the factors driving this hypotensive phenotype and therefore therapeutic interventions are limited.

Identification of chromosomal abnormalities is an important issue in animal breeding and veterinary medicine. Routine cytogenetic diagnosis of domestic animals began in the 1960s with the aim of identifying carriers of centric fusion between chromosome 1 and 29 in cattle. In the 1970s, chromosome banding techniques were introduced, and in the 1980s, the first cytogenomic techniques, based on the development of locus- and chromosome-specific probes, were used.

Trisomy 22 is a rare autosomal constitutional chromosomal disorder with high survival incompatibility being the third most frequent trisomy in spontaneous abortions and accounting for 10%-15% of all cases. Mosaic trisomy 22 is a less severe variant of the disorder associated with mild phenotype and longer lifespan compared to cases with complete trisomy 22. To date, there have only been 25 reported cases of trisomy 22 worldwide.
