The POMK gene is associated with autosomal recessive muscular dystrophy-dystroglycanopathy type A12 (MDDGA12) (MedGen UID: 815294) and type C12 (MDDGC12) (MedGen UID: 863621).

The POMT1 gene is associated with autosomal recessive muscular dystrophy-dystroglycanopathy type A1 (MDDGA1) (MedGen UID: 75553), type B1 (MDDGB1) (MedGen UID: 461765) and type C1 (MDDGC1) (MedGen UID: 332193).

The POMT2 gene is associated with autosomal recessive muscular dystrophy-dystroglycanopathy type A2 (MDDGA2) (MedGen UID: 461761), type B2 (MDDGB2) (MedGen UID: 461766) and type C2 (MDDGC2) (MedGen UID: 461768).

The PPT1 gene is associated with autosomal recessive neuronal ceroid lipofuscinosis 1 (CLN1) (MedGen UID: 340540).

The PRDM12 gene is associated with autosomal recessive hereditary sensory and autonomic neuropathy type VIII (HSAN8) (MedGen UID: 894363).

The PRDM16 gene currently has no well-established disease association; however, there is preliminary evidence supporting a correlation with autosomal dominant left ventricular noncompaction (LVNC) (MedGen UID: 349005) and dilated cardiomyopathy (DCM) (OMIM: 615373).

The PRDM8 gene currently has no well-established disease association; however, there is preliminary evidence supporting a correlation with autosomal recessive progressive myoclonic epilepsy (PMID: 22961547).
