Collection Method: clinical testing

The c.261T>A (p.N87K) alteration is located in exon 4 (coding exon 3) of the USPL1 gene. This alteration results from a T to A substitution at nucleotide position 261, causing the asparagine (N) at amino acid position 87 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
