Collection Method: clinical testing

The c.1657C>T (p.R553W) alteration is located in exon 7 (coding exon 5) of the SNRK gene. This alteration results from a C to T substitution at nucleotide position 1657, causing the arginine (R) at amino acid position 553 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
