Genes affected
ALDH1A3 (HGNC:409): (aldehyde dehydrogenase 1 family member A3) This gene encodes an aldehyde dehydrogenase enzyme that uses retinal as a substrate. Mutations in this gene have been associated with microphthalmia, isolated 8, and expression changes have also been detected in tumor cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]
ALDH1A3-AS1 (HGNC:55416): (ALDH1A3 antisense RNA 1)
