Severe microcephalyGene: ZPR1
Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with a phenotype in OMIM but not in Gene2Phenotype. There is currently not enough evidence to support a gene-disease association. This gene has been given a Red rating.
