The c.611A>G (p.N204S) alteration is located in exon 7 (coding exon 7) of the TMEM87A gene. This alteration results from a A to G substitution at nucleotide position 611, causing the asparagine (N) at amino acid position 204 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
