Familial cases of SRY-negative XX sex reversal are rare in humans, often hampering the discovery of new sex-determining genes2,3. The mouse model is also insufficient to correctly apprehend the sex-determination cascade, as the human pathway is much more sensitive to gene dosage4,5,6. Other species might therefore be considered in this respect7. In goats, the polled intersex syndrome (PIS) mutation associates polledness and intersexuality8,9. The sex reversal affects exclusively the XX individuals in a recessive manner, whereas the absence of horns is dominant in both sexes. The syndrome is caused by an autosomal gene located at chromosome band 1q43 (ref. 9), shown to be homologous to human chromosome band 3q23 (ref. 10). Through a positional cloning approach, we demonstrate that the mutation underlying PIS is the deletion of a critical 11.7-kb DNA element containing mainly repetitive sequences. This deletion affects the transcription of at least two genes: PISRT1, encoding a 1.5-kb mRNA devoid of open reading frame (ORF), and FOXL2, recently shown to be responsible for blepharophimosis ptosis epicanthus inversus syndrome (BPES) in humans11. These two genes are located 20 and 200 kb telomeric from the deletion, respectively. SN - 1546-1718 UR - https://doi.org/10.1038/ng769 DO - 10.1038/ng769 ID - Pailhoux2001 ER -
