The c.5438A>G (p.N1813S) alteration is located in exon 25 (coding exon 25) of the TUBGCP6 gene. This alteration results from a A to G substitution at nucleotide position 5438, causing the asparagine (N) at amino acid position 1813 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
