Abstract Background SRY (sex determining region of Y) is one of the important genes involved in the process of human sex determination. The disturbed sex determination caused by an SRY mutation accounts for 10% to 15% of cases with 46, XY sex reversal. Recently, 3 distal enhancers were identified upstream of the SOX9 gene. Objectives The purpose of this study was to investigate the molecular etiology of 46, XY sex reversal in 3 familial patients and a sporadic patient. Design Next-generation sequencing was used to reveal the genotype and inherited pattern. Copy number variations and single nucleotide polymorphism haplotyping were analyzed to observe the alteration of enhancers of SOX9. Transcriptional activity of SRY mutation were assessed by a dual luciferase reporting system, and nuclear translocation was observed by confocal microscopy. Results Two novel SRY gene mutations, p.Arg76Leu and p.Glu89flx15, were identified. In the pedigree with multiple patients, p.Arg76Leu mutation in SRY and p.Gly212Ser mutation in NR5A1 were identified in the proband. The heterozygous deletion far upstream of the SOX9 gene in chromosome 17 was identified in the 3 patients in this family, containing the distal enhancer eSR-A of SOX9 but not eSR-B and eALDI. The frameshift mutation p.Glu89flx15 was revealed to inhibit the transcriptional activity of the target gene, whereas the missense mutation p.Arg76Leu barely showed an effect. Conclusion In contrast to sporadic cases, inherited single nucleotide variations of SRY are not the main cause of the severe phenotype of 46, XY sex reversal, and the enhancers of SOX9 should be investigated carefully in such patients.

Male-to-female sex reversal in horses is a developmental disorder in which phenotypic females have a male genetic constitution. Male-to-female sex reversal is the second most common genetic sex abnormality, after X chromosome monosomy. All male-to-female sex reversal cases studied to date have been found to be infertile. Therefore, a screening test is particularly useful in laboratories doing DNA genotyping in horses. Our laboratory has tested > 209,000 horses for parentage using a panel of microsatellite markers and the sex marker gene amelogenin ( AMEL). Suspect XY sex reversal cases are reported females with a male profile by AMEL testing. After routine genotyping, 49 cases were detected and further tested using the sex-determining region Y ( SRY) gene, confirming the XY SRY-negative genotype of suspect sex reversal cases. When some inconsistencies arose in the initial result, a molecular panel of X- and Y-linked markers was analyzed for these samples. Of the 49 cases, 33 were confirmed as XY SRY-negative. The remaining 16 cases were identified as false-positives as a result of anomalies of AMEL testing in horses.

Abstract The sex-determining region of the Y chromosome (SRY) plays a key role in human sex determination, as mutations in SRY can cause XY sex reversal. Although some SRY missense mutations affect DNA binding and bending activities, it is unclear how others contribute to disease. The high mobility group domain of SRY has two nuclear localization signals (NLS). Sex-reversing mutations in the NLSs affect nuclear import in some patients, associated with defective importin-β binding to the C-terminal NLS (c-NLS), whereas in others, importin-β recognition is normal, suggesting the existence of an importin-β-independent nuclear import pathway. The SRY N-terminal NLS (n-NLS) binds calmodulin (CaM) in vitro, and here we show that this protein interaction is reduced in vivo by calmidazolium, a CaM antagonist. In calmidazolium-treated cells, the dramatic reduction in nuclear entry of SRY and an SRY-c-NLS mutant was not observed for two SRY-n-NLS mutants. Fluorescence spectroscopy studies reveal an unusual conformation of SRY.CaM complexes formed by the two n-NLS mutants. Thus, CaM may be involved directly in SRY nuclear import during gonadal development, and disruption of SRY.CaM recognition could underlie XY sex reversal. Given that the CaM-binding region of SRY is well-conserved among high mobility group box proteins, CaM-dependent nuclear import may underlie additional disease states.
