Ambry Genetics

Oct 27, 2022

The c.1331G>A (p.R444H) alteration is located in exon 8 (coding exon 7) of the TLDC1 gene. This alteration results from a G to A substitution at nucleotide position 1331, causing the arginine (R) at amino acid position 444 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
