The c.994T>C (p.W332R) alteration is located in exon 4 (coding exon 1) of the USP49 gene. This alteration results from a T to C substitution at nucleotide position 994, causing the tryptophan (W) at amino acid position 332 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
