Ambry Genetics

Feb 27, 2023

The c.1057T>C (p.W353R) alteration is located in exon 1 (coding exon 1) of the HCAR3 gene. This alteration results from a T to C substitution at nucleotide position 1057, causing the tryptophan (W) at amino acid position 353 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
