XX sex reversal is known in 17 breeds of dogs. In the American cocker spaniel, it segregates as an autosomal recessive trait, and the affected animals lack the testis determining Sry gene. In the search for an autosomal gene that causes this trait, we considered the possibility of Lhx9, a gene encoding LIM homeobox containing transcription factor 9, as a candidate gene. An American cocker spaniel pedigree showing Sry-negative XX sex reversal phenotype was genotyped with an intronic Lhx9 microsatellite marker. Segregation of the Lhx9 marker in the pedigree indicated that a mutation in canine Lhx9 is not likely to be the cause of Sry-negative XX sex reversal. In addition, using the recently available 7.6X canine genomic sequence, we report the location and genomic organization of canine Lhx9.
