Ambry Genetics

May 17, 2023

The c.2603T>C (p.M868T) alteration is located in exon 14 (coding exon 14) of the FAM184B gene. This alteration results from a T to C substitution at nucleotide position 2603, causing the methionine (M) at amino acid position 868 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
