Ambry Genetics

Oct 10, 2023

The c.752G>A (p.R251Q) alteration is located in exon 12 (coding exon 11) of the TPTE2 gene. This alteration results from a G to A substitution at nucleotide position 752, causing the arginine (R) at amino acid position 251 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
