Collection Method: clinical testing

The c.481C>T (p.R161C) alteration is located in exon 7 (coding exon 4) of the SSUH2 gene. This alteration results from a C to T substitution at nucleotide position 481, causing the arginine (R) at amino acid position 161 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
