Collection Method: clinical testing

The c.179T>A (p.M60K) alteration is located in exon 1 (coding exon 1) of the FAM159B gene. This alteration results from a T to A substitution at nucleotide position 179, causing the methionine (M) at amino acid position 60 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
