Collection Method: clinical testing

The c.175T>C (p.Y59H) alteration is located in exon 1 (coding exon 1) of the FAM159B gene. This alteration results from a T to C substitution at nucleotide position 175, causing the tyrosine (Y) at amino acid position 59 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
