Ambry Genetics

Aug 12, 2021

The c.899G>A (p.R300Q) alteration is located in exon 2 (coding exon 2) of the SLC35E4 gene. This alteration results from a G to A substitution at nucleotide position 899, causing the arginine (R) at amino acid position 300 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
