The c.2780A>G (p.N927S) alteration is located in exon 19 (coding exon 19) of the HEATR6 gene. This alteration results from a A to G substitution at nucleotide position 2780, causing the asparagine (N) at amino acid position 927 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
