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]

Ambry Genetics

Dec 08, 2023

The c.170G>A (p.R57Q) alteration is located in exon 2 (coding exon 2) of the ALDH1A3 gene. This alteration results from a G to A substitution at nucleotide position 170, causing the arginine (R) at amino acid position 57 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
