The c.4741G>A (p.V1581I) alteration is located in exon 22 (coding exon 22) of the USP54 gene. This alteration results from a G to A substitution at nucleotide position 4741, causing the valine (V) at amino acid position 1581 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
