Ambry Genetics

Feb 03, 2022

The c.1133G>T (p.R378L) alteration is located in exon 11 (coding exon 11) of the ITFG1 gene. This alteration results from a G to T substitution at nucleotide position 1133, causing the arginine (R) at amino acid position 378 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
