  "statement": "A systematic review of genetic data proposes that primary lipedema follows an autosomal dominant inheritance pattern with incomplete penetrance and sex-limited expression (predominantly affecting women), with positive family history self-reported in up to 64% of women, and identifies syndromic forms linked to hormonal regulators including POU1F1A (Pit-1 regulating GH, PRL, TSH) and NSD1 (potentiating androgen receptor transactivation and estrogen-mediated tissue expansion).",
