The c.1312C>T (p.H438Y) alteration is located in exon 2 (coding exon 1) of the USP51 gene. This alteration results from a C to T substitution at nucleotide position 1312, causing the histidine (H) at amino acid position 438 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
