reproductive system
azoospermia
(
J:109004
)
|
• homologous chromosomes are not assembled into the synaptonemal complex
|
• male germ cells lack double strand breaks and are defective recombination and synapsis
(J:194067)
• however, preleptotene pairing is normal
(J:194067)
|
• primary spermatocytes represent the most advanced spermatogenic cells
• arrest at the stage of pachytene-like chromosome condensation
|
• show ovarian tubulostromal hyperplasia
|
• with hyperplasia of interstitial cells
• approximately 30% of the size of the wild-type
|
infertility
(
J:109004
)
• in both sexes
• do not show gross changes in any of the 32 somatic tissues examined
• homozygous mutants are born at normal Mendelian distribution
|
endocrine/exocrine glands
• show ovarian tubulostromal hyperplasia
|
• with hyperplasia of interstitial cells
• approximately 30% of the size of the wild-type
