Collection Method: clinical testing

The c.260G>A (p.C87Y) alteration is located in exon 3 (coding exon 1) of the FBXO48 gene. This alteration results from a G to A substitution at nucleotide position 260, causing the cysteine (C) at amino acid position 87 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
