The paper investigates whether anthropometric characteristics and menstrual traits share a common genetic basis with endometriosis. Using a two-sample Mendelian randomization (2SMR) framework and publicly available GWAS data, the authors estimate genetic relationships between these traits and endometriosis, reporting that lower body weight and shorter menstrual cycle length have a genetic association with endometriosis and that the relationship may be causal. The main limitation acknowledged in such an approach is reliance on the validity of the instrumental variables and the interpretability of Mendelian randomization assumptions, though no additional caveats are detailed in the provided text. This paper is centrally about endometriosis — it tests common genetic causes linking menstrual cycle length and body weight to endometriosis.

Abstract

Endometriosia kausa ezezaguneko gaixotasun ginekologiko ohikoenetariko bat da, funtzionalki aktiboa den endometrio-ehuna umetoki-barrunbetik kanpo haztean agertzen dena. Fenotipo ugarirekin erlazionatu da, hala nola neurri antropometrikoekin eta ezaugarri menstrualekin. Hala ere, ez da oraindik ezagutzen azken horiek eta endometriosiak oinarri genetiko bera partekatzen duten. Genetika komun hori aztertzeko, bi lagineko ausazkotze mendeldarraren (2SMR) analisia egin genuen, GWAS ikerketetako datu publikoak erabiliz. Gure emaitzen arabera, pisu baxuak eta hilekoaren ziklo laburrek endometriosiarekin harreman genetikoa dute. Are gehiago, badirudi erlazio hori kausala izan litekeela. * IKERGAZTE 2021eko lan saritua
