qPCR (copy number calculated) illustrating the IL7R gene deletion in the family. IL7R-qe1, IL7R-qe4, and IL7R-qe9 are three distinct regions of IL7R gene. Bar graph shows the calculated copy numbers of DNA from the proband, her father, mother, sister, and normal control by qPCR. The copy number decreased by half in the proband, her father, and sister as compared to the normal control, suggesting a heterozygous deletion of IL7R gene
