So I just did some research and people with down syndrome do have fingerprints, albeit specific ones.
"people with Down syndrome have a fingerprint pattern with mainly ulnar loops, and a distinct angle between the triradia a, t, and d (the 'adt angle'). Other differences include a single transverse palmar crease ("Simian line") (in 50% of patients), patterns in the hypothenar and interdigital areas, and lower ridge counts along digital midlines, especially in little fingers, which corresponds to finger shortening in those with Down syndrome."
