Ambry Genetics

Jan 23, 2023

The c.607C>T (p.R203W) alteration is located in exon 3 (coding exon 3) of the FAM107B gene. This alteration results from a C to T substitution at nucleotide position 607, causing the arginine (R) at amino acid position 203 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
