In the second, a genome- wide analysis of single nucleotide polymorphisms (SNPs) from field-collected red corals (Corallia rubrum) yielded several male-specific loci consistent with chromosomal XX/XY sex determination [15]. The hydroid Hydractinia symbiolongicarpus is a prom- ising laboratory model...
This limits our ability to infer the evolutionary history of sex determination within animals. Results In this study, we generated a linkage map of the genome of the colonial cnidarian Hydractinia symbiolongicarpus and used it to demonstrate that this species has an XX/XY sex determination system...
22,28). Homology between XX/XY sex chromosomes with dissimilar morphology in representatives from the genusChelodinawhen compared withElseyaandEmyduramight be supported by accumulation of the same repetitive motifs (GATA microsatellite, rDNA, telomeric-like sequences) in at least some...
Here we describe an XY sex-reversed female with pure gonadal dysgenesis who harbors a de novo nonsense mutation in the SRY open reading frame (SRY-orf). This single-basepair substitution results directly in the formation of a termination codon in the putative SRY DNA-binding motif, presumably ...

This study has focused on an inherited mutation in the HMG box of SRY associated in the proband with somatic XY sex reversal, primary amenorrhea, and gonadoblastoma in situ (63). The same mutation was found in the Y chromosomes of the proband's father, fertile paternal uncle, and two br...
Background 46,XY sex reversal is a rare disorder and familial cases are even more rare. The purpose of the present study was to determine the molecular basis for a family with three affected siblings who had 46,XY sex reversal. Methods \\{DNA\\} was extracted from three females with 46...
