Objective: This study was aimed to identify a rare complex rearrangement and assist prenatal counseling.
Method: Mate-pair sequencing (MPseq) combined with karyotypes, copy number variants sequencing and whole exome sequencing was used to provide accurate chromosome breakpoints and assist prenatal diagnosis for a mentally retarded pregnant woman.
Result: MPseq indicated a complex rearrangement involved 25 breakpoints and fusions, disrupting 6 genes. Among which, ZMIZ1 was associated with neurodevelopmental disorders with dysmorphic facies and distal skeletal abnormalities, which was consistent with the phenotype of pregnant women.
Conclusion: MPseq was a cost-effective and accurate method that could be used as a complementary tool for human genetic diagnosis and prenatal counseling.

Silver-Russell Syndrome (SRS) is a genetic disorder characterized by intrauterine and postnatal growth restriction. Most cases are caused by an imprinting error either with hypomethylation of the Imprinted Control Region 1 at 11p15.5, or maternal uniparental disomy of chromosome 7.

Background: Mate-pair sequencing detects both balanced and unbalanced structural variants (SVs) and simultaneously informs in relation to both genomic location and orientation of SVs for enhanced variant classification and clinical interpretation, while chromosomal microarray analysis (CMA) only reports deletion/duplication. Herein, we evaluated its diagnostic utility in a prospective back-to-back prenatal comparative study with CMA.
Methods: From October 2021 to September 2023, 426 fetuses with ultrasound anomalies were prospectively recruited for mate-pair sequencing and CMA in parallel for prenatal genetic diagnosis.

Introduction: rearrangement () is a common genomic alteration in acute leukemia that can be effectively targeted by menin inhibitors. While FISH is the standard laboratory test for , false positives can occur.
Case Report: We present a case of AML in which both and were identified by karyotype analysis and FISH.
