Article Abstract
The landscape of chromosomal aberrations in the tumor cells of the patients with B-ALL is diverse and can influence the outcome of the disease. Molecular karyotyping at the onset of the disease using chromosomal microarray (CMA) is advisable to identify additional molecular factors associated with the prognosis of the disease. Molecular karyotyping data for 36 patients with Ph-negative B-ALL who received therapy according to the ALL-2016 protocol are presented. We analyzed copy number alterations and their prognostic significance for /, , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , and genes, choosing t(4;11) and t(7;14) as reference events. Of the 36 patients, only 5 (13.8%) had a normal molecular karyotype, and 31 (86.2%) were found to have various molecular karyotype abnormalities-104 deletions, 90 duplications or amplifications, 29 cases of cnLOH and 7 biallelic/homozygous deletions. We found that 11q22-23 duplication involving the , and genes was the most adverse prognostic event in the study cohort.

Introduction: Spinal muscular atrophy (SMA), caused by pathogenic variants in the survival motor neuron (SMN) gene, is the most common genetic cause of mortality in children under the age of two. Prior reports of obstetric sonograms performed in pregnancies with severe forms of fetal SMA have discrepant findings that may stem from a failure to account for the SMN2 copy number.
Methods: We present a neonate diagnosed with SMA type 0 postnatally (0SMN1/1SMN2 genotype).

SLICK1 is an allelic variant of the prolactin receptor () that is found in Senepol beef cattle. The presence of a single copy of this allele produces a short hair coat and confers heat tolerance. We aimed to determine the effect of 2 copies of this allele on milking performance of dairy cattle.

Introduction: Mitochondrial DNA (mtDNA) copy number variations have been reported in multiple human cancers. Previous studies indicate that mitochondrial retrograde signaling regulates , which plays a key role in tumorigenesis, including regulating apoptosis antagonizing transcription factor (). This study investigates the expression of and in relation to mtDNA copy number in invasive ductal carcinoma (IDC) of the breast.

Miniature inverted-repeat transposable elements (MITEs) are short, non-autonomous class II transposable elements prevalent in eukaryotic genomes, contributing to various genomic and genic functions in plants. However, research on MITEs mainly targets a few species, limiting a comprehensive understanding and systematic comparison of MITEs in plants. Here, we developed a highly sensitive MITE annotation pipeline with a low false positive rate and applied it to 207 high-quality plant genomes.
