The c.2585A>G (p.N862S) alteration is located in exon 18 (coding exon 17) of the TUBGCP2 gene. This alteration results from a A to G substitution at nucleotide position 2585, causing the asparagine (N) at amino acid position 862 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
