Anauxetic Dysplasia 1, also known as anauxetic dysplasia, is related to metaphyseal dysplasia without hypotrichosis and anauxetic dysplasia 2. An important gene associated with Anauxetic Dysplasia 1 is RMRP (RNA Component Of Mitochondrial RNA Processing Endoribonuclease), and among its related pathways/superpathways are Processing of Capped Intron-Containing Pre-mRNA and rRNA processing in the nucleus and cytosol. Affiliated tissues include spinal cord and bone, and related phenotypes are macroglossia and microdontia
