Hemifacial myohyperplasia (HFMH) es un maladia rar characterisate per muscular hypertrophia, mitochondrial dysfunctionamento e hypoglycemia. Es causate per un mutation del gene PIK3CA, un gene etiam implicate in syndrome CLOVES (fr).

Un tractamento con alpelisib (en), un inhibitor del gene PIK3CA utilisate in CLOVES syndrome, permitte de recuperar un symetrisation progressive del facie.^[1]^[2]
