Heimler syndrome-1 (HMLR1), which represents the mildest end of the peroxisomal biogenesis disorder spectrum (see PBD1A, 214100), is a rare autosomal recessive disorder characterized by sensorineural hearing loss, enamel hyoplasia of the secondary dentition, and nail abnormalities (Ratbi et al., 2015). Genetic Heterogeneity of Heimler Syndrome Another form of Heimler syndrome (HMLR2; 616617) is caused by mutation in the PEX6 gene (601498) on chromosome 6p21. [from OMIM]
