Abstract
The aim of the study was to detect the frequency of the CFTR gene variants poly-T, TG repeats and c.1408A>G p.Met470Val (M470V) in Indian men with congenital bilateral absence of the vas deferens (CBAVD). Men diagnosed with CBAVD (n = 76), their female partners (n = 76) and healthy men from general population (n = 50) were recruited. Genomic DNA was isolated and the polymorphic regions of IVS9- c.1210-12T [5] and M470V were amplified using specific primers followed by Sanger's DNA sequencing. A statistically significant increase in the frequency of heterozygous IVS9- c.1210-12T [5] (39.4%) was observed in CBAVD men as compared to controls (14%). The allelic distribution of c.1210-12T [5], c.1210-12T [7] and c.1210-12T [9] in CBAVD men was 21%, 64.4% and 13% and that in healthy controls was 7%, 73% and 20% respectively. Longest TG repeat c.1210-34TG [13] was found in association with c.1210-12T [5] with an allelic frequency of 5.9% in CBAVD men. We found a significant association of c.1210-34TG [12]/c.1210-34TG [13] - c.1210-12[5] -V470 allele in CBAVD men. Twelve female partners harboured a heterozygous c.1210-12T [5] allele. The study emphasises the need to screen both partners for the polymorphisms M470V, poly-T, TG tract repeats in addition to population-specific known CFTR gene mutations.

Abstract
Endometriosis is defined as the growth of endometrial glands and stroma in ectopic locations. Its aetiology is multifactorial, but autoimmunity has been shown to play a role in its onset and development. The present study aimed to investigate the presence of both IgG and IgM anti-endometrial antibodies in sera of endometriosis patients in comparison with age-matched controls, and to also investigate the cognate endometrial proteins involved. Sera from these groups were screened by western blot and immunohistochemistry. Thirteen out of the 40 sera tested were positive for IgG isotype, and 10/27 IgG negative patients were positive for IgM isotype. These findings indicate that endometrial antibodies of IgG and IgM classes could be detected in almost 60% of endometriosis patients. Of the various identified endometrial antigens, 30 and 45 kDa antigens were immunodominant in both IgG and IgM positive endometriosis patients. With immunohistochemistry, positive sera showed reactivity in luminal epithelium, glandular epithelium and stroma. These anti-endometrial antibodies might be partially responsible for failure of implantation leading to infertility. Identification of specific targets would be a help in understanding the pathophysiology of endometriosis, and would also help in setting up a non-invasive test for the diagnosis of endometriosis.
