Ambry Genetics

Nov 09, 2021

The c.750G>C (p.R250S) alteration is located in exon 1 (coding exon 1) of the TMEM81 gene. This alteration results from a G to C substitution at nucleotide position 750, causing the arginine (R) at amino acid position 250 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
