These mutations lead to characteristic features including macrocephaly, intestinal hamartomatous polyps, benign skin tumors (multiple trichilemmomas, papillomatous papules, and acral keratoses) and dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease).

Dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease) occurs in the setting of Cowden disease, which is associated with a germline mutation of the gene PTEN/MMAC1 (located on 10q23).

Lhermitte-Duclos disease (dysplastic gangliocytoma of the cerebellum, LDD) is a rare, slowly growing tumor of the cerebellum, sometimes considered as hamartoma, characterized by diffuse hypertrophy of the stratum granulosum of the cerebellum.
