26098692 Among Systemic lupus erythematosus patients, 63.6% and 45.5% of those with lupus nephritis were positive for anti-RRP8 and anti-TNP1 antibodies, compared with 12.5% and 9.4% of Systemic lupus erythematosus patients without nephritis, respectively.
20522125 frequency of the haplotype GCG (H3) was increased in azoospermic men compared with fertile men. expression analysis of the TNP1 gene in obstructive azoospermic men showed that haplotypes of the TNP1 gene do not affect its expression level.

18727729 The presence of transition proteins (TP1 and/or TP2) in spermatids in semen indicates inhibition in the differentiation pathway from round spermatids to spermatozoa in infertile men.
18292840 The TNP1 contributes not only to successful fertilization, but may has an important impact in development of preimplantation embryos.
17852044 We found significantly lower levels of HILS1, TNP1, and TNP2 transcripts in spermatozoa from asthenozoospermic men compared to normozoospermic men.

16291974 Observational study of gene-disease association. (HuGE Navigator)
16291974 a deletion of 15 nucleotides encompassing the recognition site for the cAMP response element transcription factor was found in the 5'-promoter region of the TNP1 gene in infertile men; this deletion reduces TNP1 expression and may cause infertility
