The c.3587G>A (p.S1196N) alteration is located in exon 11 (coding exon 11) of the CAMSAP1 gene. This alteration results from a G to A substitution at nucleotide position 3587, causing the serine (S) at amino acid position 1196 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
