General Comment NCBI Summary: This gene encodes a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motif) protein family. Members of the family share several distinct protein modules, including a propeptide region, a metalloproteinase domain, a disintegrin-like domain, and a thrombospondin type 1 (TS) motif. Individual members of this family differ in the number of C-terminal TS motifs, and some have unique C-terminal domains. The protein encoded by this gene has high sequence similarity to the protein encoded by ADAMTS16, another family member. [provided by RefSeq, Jul 2008]

Comment Comparison of Serum A Disintegrin and Metalloproteinase with Thrombospondin Motifs-19 Levels in Different Fertility Situations: Could It Be a Serum Marker of Ovarian Function and Oocyte Pool? Ersoy E et al. (2018) A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) enzymes take part in extracellular matrix (ECM) remodeling which has been shown to contribute to the ovulation and follicular functions. We aimed to compare serum levels of ADAMTS-19 in patients with different fertility situations. A total of 86 women were enrolled to this cross sectional and case-control study. Four groups were constituted with respect to women's clinical and hormonal status: group 1, women with premature ovarian failure (POF; n = 21); group 2, women with natural menopause (n = 21); group 3, women with polycystic ovary syndrome (PCOS; n = 22); and group 4, healthy fertile controls. Serum ADAMTS-19 levels and individual characteristics were compared among groups. -ADAMTS-19 levels were found as 36.7 ± 10.2, 40.1 ± 12.6, 46.7 ± 16.1, and 51.0 ± 18.8 ng/mL in POF, fertile, natural menopause, and PCOS groups, respectively (p = 0.012). Especially, ADAMTS-19 levels in the PCOS group were significantly higher than the POF group, as found in dual comparisons (p = 0.010). ADAMTS-19 was found to be higher in PCOS patients than in POF patients. This work provides a novel vantage point for function of ECM within the ovary. ADAMTS-19 may have a potential for being an important marker of ovarian function and oocyte pool.//////////////////

Comment: Genome-wide association study in premature ovarian failure patients suggests ADAMTS19 as a possible candidate gene. Knauff EA et al. BACKGROUND: Spontaneous premature ovarian failure (POF) occurs in 1% of women and has major implications for their fertility and health. Besides X chromosomal aberrations and fragile X premutations, no common genetic risk factor has so far been discovered in POF. Using high-density single nucleotide polymorphism (SNP) arrays, we set out to identify new genetic variants involved in this condition. METHODS: A genome-wide association study involving 309 158 SNPs was performed in 99 unrelated idiopathic Caucasian POF patients and 235 unrelated Caucasian female controls. A replication study on the most significant finding was performed. We specifically focused on chromosomal areas and candidate genes previously implicated in POF. RESULTS: Suggestive genome-wide significant association was observed for rs246246 (allele frequency P = 6.0 x 10(-7)) which mapped to an intron of ADAMTS19, a gene known to be up-regulated in the female mouse gonads during sexual differentiation. However, replication in an independent Dutch cohort (60 POF patients and 90 controls) could not confirm a clear association (P = 4.1 x 10(-5) in a joint analysis). We did not observe strong evidence for any of 74 selected POF candidate genes or linkage regions being associated with idiopathic POF in Caucasian females, although suggestive association (P < 0.005) was observed for SNPs that mapped in BDNF, CXCL12, LHR, USP9X and TAF4B. CONCLUSION: We observed a possible association between POF and a SNP in a biologically plausible candidate gene. Although limited by sample size, this proof-of-principle study's findings reveal ADAMTS19 as a possible candidate gene for POF and thus a larger follow-up study is warranted.

Comment: Epistasis between IGF2R and ADAMTS19 polymorphisms associates with premature ovarian failure. Pyun JA 2013 et al. STUDY QUESTION Do single nucleotide polymorphisms (SNPs) or synergistic interactions between SNPs and diplotypes within the insulin-like growth factor 2 receptor (IGF2R) and ADAM metallopeptidase with thrombospondin type 1 motif, 19 (ADAMTS19), contribute to premature ovarian failure (POF)? SUMMARY ANSWER Synergistic interactions were detected between SNPs, including a non-synonymous SNP, and diplotypes within IGF2R and ADAMTS19 which may contribute to POF; however, there was no correlation with POF in a single SNP model after Bonferroni correction. WHAT IS KNOWN ALREADY IGF2R regulates free IGF2 level, which is involved in steroidogenesis in bovine granulosa cells. ADAMTS19 expression is higher in the murine embryonic ovary than in the embryonic testis during sexual differentiation, and an ADAMTS19 SNP (rs246246) showed a possible association with POF in a genome-wide association study in Caucasian women. STUDY DESIGN, SIZE, DURATION This study analyzed interactions between SNPs and diplotypes within IGF2R and ADAMTS19 as well as SNPs within the two genes. In Stage I, a total of 120 patients with POF and 152 female controls were recruited. All patients were diagnosed with POF at the CHA hospital in Seoul, Korea, and were recruited between 1994 and 2004. The 152 controls were recruited from Chungju, Korea, as part of another study that was conducted from April 2002 to March 2004. For Stage II, we obtained genotype data for an additional 1641 female controls, recruited in Ansung and Ansan from 2001 to 2008, from the Korean Genome Epidemiology Study (KoGES). PARTICIPANTS/MATERIALS, SETTING, METHODS In Stage I, the GoldenGate assay with VeraCode technology was used to genotype SNPs in IGF2R and ADAMTS19. In Stage II, we obtained genotype data for IGF2R and ADAMTS19 using Affymetrix Genome-Wide Human SNP array 5.0 and imputed data by the IMPUTE program from the KoGES. To identify POF-associated SNPs, logistic regression analysis in an additive model was performed using the PLINK tool. Synergistic interactions between SNPs and diplotypes within IGF2R and ADAMTS19 were analyzed by logistic regression analysis in three alternative models. MAIN RESULTS AND THE ROLE OF CHANCE In Stage I, 13 combinations of SNPs showed significant synergistic interactions after Bonferroni correction [the strongest association had odds ratio (OR) = 5.77, 95% confidence interval (CI): 2.26-14.75, P = 0.00025]. In Stage II and combined analyses, two and four combinations, respectively, of the significant results in Stage I showed significant synergistic interactions after Bonferroni correction. For interactions between diplotypes in block 2 of IGF2R and block 3 of ADAMTS19 in Stage I, we found 17 synergistic interactions with P < 0.0001, but there was no significant interaction after Bonferroni correction. In Stage II and combined analyses, we found that three and seven combinations in the same blocks, respectively, showed significant synergistic interactions after Bonferroni correction (strongest association: OR = 4.12, 95% CI: 2.22-7.62, P = 6.74E-06). LIMITATIONS, REASONS FOR CAUTION The sample size for patients with POF in this study was small but, compared with recent reports describing associations between SNPs and POF and considering the low prevalence of POF (1%), the sample size is considered to be reasonable. These results should be confirmed in large-scale studies involving different ethnic groups. WIDER IMPLICATIONS OF THE FINDINGS Our results may ultimately provide predictive markers for women at a high risk of POF. STUDY FUNDING/COMPETING INTERESTS This study was supported by grants from Basic Science Research Program through the National Research Foundation of Korea (NRF), which is funded by the Ministry of Education (2009-0093821, 2011-0010637). There are no competing interests. /////////////////////////
