Genes affected

RAI2 (HGNC:9835): (retinoic acid induced 2) Retinoic acid plays a critical role in development, cellular growth, and differentiation. The specific function of this retinoic acid-induced gene has not yet been determined but it may play a role in development. The chromosomal location of this gene designates it to be a candidate for diseases such as Nance-Horan syndrome, sensorineural deafness, non-specific X-linked cognitive disability, oral-facial-digital syndrome, and Fried syndrome. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2010]

The c.1420G>C (p.V474L) alteration is located in exon 3 (coding exon 1) of the RAI2 gene. This alteration results from a G to C substitution at nucleotide position 1420, causing the valine (V) at amino acid position 474 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
