This systematic review reports specific genetic findings in lipedema including an AKR1C1 missense variant (Michelini 2020) associated with reduced progesterone clearance and increased adipogenesis, a familial Pit1 mutation causing GH and testosterone deficiency (Bano 2010), and upregulation of ZNF423 and CAV1 dysfunction, supporting a possible genetic susceptibility component.

Evidence (2)
- Impact of hormones on lipedema development: a systematic literature review — Lüchinger et al. (2026) ✓ verified — consistent · review · 2026 · reading confidence: moderate
“AKR1C1 missense variant (Michelini 2020): clearance de progesterona reduzido, aumento adipogênese via ADD1/SREBP1c, redução PGF2”
The review explicitly cites a familial genetic study and a specific AKR1C1 missense variant plus other gene-level findings (ZNF423, CAV1), directly bearing on genetic variants in lipedema, though genetics is a secondary focus of this hormon - Lipedema Research—Quo Vadis? — Ernst et al. (2023) ✓ verified — consistent · review · 2023 · reading confidence: high
“Variante missense no gene AKR1C1 (aldo-ceto redutase envolvida no metabolismo da progesterona) — primeiro gene mutado identificado em família com lipedema primário não sindrômico”
The review explicitly describes inheritance patterns (X-linked dominant/autosomal dominant with incomplete penetrance, oligogenic) and names a specific variant (AKR1C1 missense) identified in primary lipedema, directly addressing the questi [grade capped moderate->very_low per curated Oxford N6]
