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)

Submissions by phenotype

Isolated anophthalmia-microphthalmia syndrome Pathogenic:1
Pathogenic, criteria provided, single submitterin vitroMedical Genetics Laboratory, West China Hospital, Sichuan University-We investigated a newborn with bilateral anophthalmia in a Chinese family. Exome sequencing revealed that compound heterozygous mutations c.287G>A (p.(Arg96His)) and c.709G>A (p.(Gly237Arg)) of the ALDH1A4 gene were presented in the affected newborn. These mutations were confirmed to be transmitted from the parents respectively. In vitro expression showed that both mutations decreased the protein production and impaired the protein tetramer formation. -
