By cotransfecting human SRY (encoded on the male Y chromosome), the efficiency of the 420M9-1395 intronic region to drive transcription was reduced by around 15% ( Figure 5 ), and the combination of both SRY and the novel haplotype further reduced expression over wild type at a trend level of significance ( t =1.7675, df=9, P =0.055).
