Ambry Genetics

Dec 14, 2022

The c.69G>T (p.R23S) alteration is located in exon 1 (coding exon 1) of the ARHGEF38 gene. This alteration results from a G to T substitution at nucleotide position 69, causing the arginine (R) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
