Phenotype of patients and controls bearing gr/gr and *b2/b3 deletions. The entire coding region of DAZL was sequenced, and no mutation was found except the single nucleotide polymorphism A→G transition in exon 2 (SNP 260). Patient A46 had undergone surgery at the age of 2 years for unilateral cryptorchidism
