Ambry Genetics

Sep 27, 2021

The c.920G>A (p.R307H) alteration is located in exon 4 (coding exon 3) of the TMEM198 gene. This alteration results from a G to A substitution at nucleotide position 920, causing the arginine (R) at amino acid position 307 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
