Copy number variation regions (CNVRs) detected in the genome of children from Salvador, Brazil. Copy number variations in the genome of 872 individuals from the SCAALA-Salvador cohort were inferred from SNP microarray data (Illumina HumanOmni 2.5–8v1 panel), using algorithms implemented in PennCNV v1.0.1 and QuantiSNP v2.0. Deletions or duplications showing sequence overlap were grouped into a single CNVR. (A) Number (#) of CNVRs detected by PennCNV and QuantiSNP (after quality control). Only CNVRs detected by both algorithms were considered for further analysis. (B) Frequency of deletions and duplications (<1% or ≥1%) in the study population. (C) Size of the deletions and duplications (bp, base pair), violin plots. (D) Number (#) of CNVRs by human autosomal chromosome.
