Denne kromosomfeilen kommer av en ekstra versjon av X-kromosomet.Den normale kjønnskromosomkonfigurasjonen til menn er 46,XY. Hos individer med Klinefelters syndrom gir det ekstra X-kromosomet en ekstra mengde arvemateriale i alle cellene i kroppen Klinefelters syndrom er en medfødt kromosomfeil hos menn. Feilen består i at kjønnskromosomparet XY er erstattet med XXY (to kvinnelige og ett mannlig kjønnskromosom). Det ekstra X-kromosomet kommer like ofte med sædcellen som med eggcellen.
