Although the primary focus of the study was to identify genetic variants influencing these metabolic and biochemical profiles, early evidence positions RTL4 as a candidate potentially involved in the regulation of lipid and metabolic homeostasis. Its association with traits indicative of lipid metabolism suggests that RTL4 may modulate aspects of cholesterol transport or synthesis, processes that are integral to maintaining overall metabolic balance. The study’s design, which leverages a population enriched for rare variants of large effect, paves the way for deeper functional investigations that could clarify RTL4’s precise regulatory role in these biochemical pathways."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Tatijana Zemunik, Mladen Boban, Gordan Lauc, et al.
