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

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2023The c.487G>A (p.V163M) alteration is located in exon 5 (coding exon 5) of the ALDH1A3 gene. This alteration results from a G to A substitution at nucleotide position 487, causing the valine (V) at amino acid position 163 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
