Collection Method: clinical testing

The c.35A>G (p.Y12C) alteration is located in exon 1 (coding exon 1) of the FAM159B gene. This alteration results from a A to G substitution at nucleotide position 35, causing the tyrosine (Y) at amino acid position 12 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
