Ambry Genetics

Jan 20, 2023

The c.310C>T (p.R104W) alteration is located in exon 2 (coding exon 2) of the ALKBH4 gene. This alteration results from a C to T substitution at nucleotide position 310, causing the arginine (R) at amino acid position 104 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
