Ambry Genetics

May 07, 2024

The c.1157G>A (p.R386H) alteration is located in exon 4 (coding exon 4) of the TMCC3 gene. This alteration results from a G to A substitution at nucleotide position 1157, causing the arginine (R) at amino acid position 386 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
