Ambry Genetics

Oct 12, 2021

The c.71G>A (p.R24H) alteration is located in exon 2 (coding exon 2) of the SLC44A1 gene. This alteration results from a G to A substitution at nucleotide position 71, causing the arginine (R) at amino acid position 24 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
