Although this was reported to cover 99% of the euchromatic human genome with 99.99% accuracy, a major quality assessment of the human genome sequence was published on May 27, 2004 indicating over 92% of sampling exceeded 99.99% accuracy which was within the intended goal.
Aínda que se informara que comprendía o 99% do xenoma humano eucromático cunha exactitude do 99,99%, despois publicouse unha avaliación de maior calidade posterior da secuencia do xenoma humano o 27 de maio de 2004 na que se indicaba que o 92% das mostras superaban o 99,99% de exactitude o que estaba dentro do obxectivo buscado.
