    “…Substantial differences were found among 1,16-chromogroups in terms of other chromosomal aberrations, aneuploidy scores, transcriptomic data, single-point mutations, histotypes, and molecular subtypes. Breast cancers with a co-occurrence of 1q-gain and 16q-loss can be distinguished in a “low aneuploidy score” group, congruent to der(1;16), and a “high aneuploidy score” group, congruent to the co-occurrence of isochromosome 1q and deleted 16q. …”

    “…However functional characterization of these variants and their integrations with other viral proteins including variability of human receptors (ACE2 & NRP1) may be the other reasons for unlikely COVID-19 statistics in Pakistan which need further confirmatory studies. Moreover, mutated N and ORF1a proteins in Pakistani strains were also analyzed by 3D structure modeling, which give another dimension of comparing these alterations at amino acid level. …”
