Associated with Acrofacial dysostosis, Cincinnati type (#616462) in OMIM and Gene2Phenotype (probable).
PMID: 25913037 - Weaver et al. 2015 - report 3 individuals with mandibulofacial dysostosis, 2 of which have limb anomalies. All have putative pathogenic variants in POLR1A. Limb anomalies include short stature with congenital short bowed femurs with metaphyseal flaring, dysplastic acetabulae, and delayed or absent ossification of the capital femoral epiphyses in Individual 1A1, and short, broad fingers and toes in individual 1A3. polr1a mutant zebrafish exhibited cranioskeletal anomalies mimicking the human phenotype.Created: 7 Aug 2019, 10:59 a.m. | Last Modified: 7 Aug 2019, 10:59 a.m.
