abstractText | Phenotypic parallels and genetic evidence from comparative mapping suggest that the murine Small eye (Sey) and human aniridia (AN) disorders are homologous. This report describes the isolation of a murine embryonic cDNA that is structurally homologous to the AN cDNA were recently cloned. The murine cDNA detects a 2.7-kb transcript in the adult mouse eye and cerebellum and in human glioblastomas, suggesting a neuroectodermal involvement in the etiology of Sey/AN. Sequence comparison between the murine and the human cDNAs revealed extensive homology in nucleotide sequence (greater than 92%) and virtual identity at the amino acid level. None of the differing amino acids was located within the paired box and homeobox DNA-binding domains. These results provide evidence for a common molecular basis underlying the two genetic disorders and suggest that the Sey system would be an authentic model for human AN. |
