TEX11 and Testicular atrophy: Tex11 was identified as one of the X-linked testis-specific genes in a genomic screen [6].Alterations in TEX11 were first described using high-resolution comparative genomic hybridization, with the loss of three exons (exons 10–12; (c.652del237bp)) in two azoospermic patients (one with mixed testicular atrophy and one with a meiotic arrest phenotype) [7].
