Ambry Genetics

Feb 28, 2023

The c.799G>C (p.D267H) alteration is located in exon 4 (coding exon 3) of the THUMPD3 gene. This alteration results from a G to C substitution at nucleotide position 799, causing the aspartic acid (D) at amino acid position 267 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
