This is a report on a 43-year-old woman in whom a mongoloid fetus could be diagnosed at the 26th week of pregnancy, following amniocentesis in the 23rd week. The interruption of pregnancy at first desired was later refused by the patient for reasons of conscience and the pregnancy carried to term. The lessons and conclusions to be drawn from this case are discussed.

Objective: To explore the genetic characteristics of a Chinese pedigree with rare mosaic 11q partial duplication and its pathogenetic mechanisms.
Methods: A pedigree which underwent prenatal diagnosis at Wenzhou Central Hospital between September 25, 2015 and November 30, 2023 was selected for the study. Clinical data were collected from the pedigree.

Objective: To explore the genotype-phenotype correlation in a Charcot-Marie-Tooth type 2A2A (CMT2A2A) pedigree and to provide genetic counseling for its subsequent pregnancies.
Methods: A Chinese pedigree presenting with "lower limb muscle atrophy and movement disorders" at the Prenatal Diagnosis Center of Xuzhou Central Hospital between January and August 2024 was selected as the study subject. Relevant clinical data were collected from the pedigree members.

Introduction: This study aimed to construct consolidated and updated ultrasonographic fetal biometry and estimated fetal weight (EFW) references for the Hong Kong Chinese population and evaluate the extent of under- and overdiagnosis of small-for-gestational-age (SGA) and large-for-gestational-age (LGA) using these new references.
Methods: Fetal biometry and EFW references were constructed using the Generalised Additive Model for Location, Scale, and Shape, based on data from 1679 singleton pregnancies in non-smoking Chinese women. Ultrasound scans were performed at 12 to 40 weeks of gestation to measure biparietal diameter, head circumference, abdominal circumference (AC), and femur length, following standardised protocols.

Objective: To explore the clinical phenotype and genetic characteristics of two siblings with intellectual disability.
Methods: Clinical data and peripheral blood samples were collected from the proband, his younger sister and parents whom had presented at Wenzhou Central Hospital in February 2024. Low-coverage massively parallel copy number variation sequencing (CNV-seq) and whole exome sequencing (WES) were carried out for the family.
