Collection Method: clinical testing

The c.29C>A (p.S10Y) alteration is located in exon 1 (coding exon 1) of the RIT2 gene. This alteration results from a C to A substitution at nucleotide position 29, causing the serine (S) at amino acid position 10 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
