Collection Method: clinical testing

The c.1202G>A (p.C401Y) alteration is located in exon 11 (coding exon 11) of the RTKN2 gene. This alteration results from a G to A substitution at nucleotide position 1202, causing the cysteine (C) at amino acid position 401 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
