PIK3CA and CLOVES syndrome: In a series of pediatric patients with LMs, Luks et al. identified PIK3CA gene mutations in patients with sporadic LMs in 16 out of 17 patients (94%) or syndromic LMs such as the Klippel–Trenaunay syndrome in 19 out of 21 patients (90%), fibro-adipose vascular anomaly in 5 out of 8 patients (63%), along with the CLOVES syndrome in 31 out of 33 patients (94%) (Luks et al., 2015).
