Although our understanding of the extent of this variation is still developing, it seems likely that, at least in humans, copy number variants (CNVs) account for a substantial amount of genetic variation." == French == === Pronunciation === IPA(key): /ɛ̃.vɛʁ.sjɔ̃/ === Noun === inversion f (plural inversions) inversion deviance (especially sexual) Synonym: déviance === Further reading === “inversion”, in Trésor de la langue française informatisé [Digitized Treasury of the French Language], 2012 == Venetan == === Etymology === Compare Italian inversione === Noun === inversion f (invariable) inversion (all senses) reversal, reversing
