Nucleotide change:

G5549683A

Amino acid change:

W293term | mia-PA; W293term | mia-PB; W293term | mia-PC

Reported amino acid change:

W297term

Comment:

G to A nucleotide change at the second or third position of the wild type Trp codon leads to a nonsense mutation (exact site of mutation unspecified). The mutation was annotated at the second base of the codon.

      Reference

      Early stages of spermatogenesis up through mature primary spermatocytes are present and normal. Postmeiotic stages are completely absent. Mutant testes have an abundance of mature primary spermatocytes with large, round nuclei and prominent nucleoli. Spermatocytes arrest in the G2/M transition of meiosis I with partial chromosome condensation.
