A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
Autosomal recessive inheritance (Orphanet)
 
Related genes: PEX6, PEX1
 
OMIM®: 234580
Orphanet: ORPHA3220

Definition

This syndrome is characterized by sensorineural hearing loss, generalized enamel hypoplasia of the permanent dentition with normal primary dentition and nail defects (Beau''s lines and leukonychia). Less than 10 patients have been described so far. Transmission is autosomal recessive. [from SNOMEDCT_US]
