This systematic review reports familial incidence of lipedema in 15% of first-degree female relatives consistent with X-linked dominant or autosomal dominant inheritance with incomplete penetrance, identifies an AKR1C1 missense variant (a gene involved in progesterone metabolism) as the first mutated gene in a family with primary non-syndromic lipedema, and notes hormonal/progesterone-pathway involvement.

“Incidência familiar em 15% de familiares femininas de primeiro grau (herança X-linked dominante ou autossômica dominante com penetrância incompleta, possivelmente oligogênica)”
The review explicitly documents familial inheritance patterns and a hormone-metabolism gene (AKR1C1, progesterone pathway) variant linked to lipedema, directly bearing on the role of heredity and hormones in onset. [grade capped moderate->very_low per curated Oxford N6]
Context (PECO)
Answers these questions
- Do hormones and heredity influence the onset of lipedema? consistent
- Do hormonal factors (puberty, pregnancy, menopause, estrogen) trigger or influence lipedema onset? consistent
- Is lipedema onset influenced by heredity and family history? consistent
