The c.26A>G (p.N9S) alteration is located in exon 2 (coding exon 1) of the TCP11L1 gene. This alteration results from a A to G substitution at nucleotide position 26, causing the asparagine (N) at amino acid position 9 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
