The c.509C>A (p.T170N) alteration is located in exon 5 (coding exon 2) of the KSR1 gene. This alteration results from a C to A substitution at nucleotide position 509, causing the threonine (T) at amino acid position 170 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
