In brief: YES

Several genetic defects that affect the development of t lymphocytes (immune system blood cells) results in absent or very small thymus.
Also, deletion of chromosome 22q11 or digeorge syndrome, a relatively common genetic syndrome, causes poor devlopment of thymus, which is significant in 1% of babies with this chromosomal deletion.
