Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1516C>T (p.R506W) alteration is located in exon 4 (coding exon 3) of the RUSC1 gene. This alteration results from a C to T substitution at nucleotide position 1516, causing the arginine (R) at amino acid position 506 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
