The c.800G>A (p.R267Q) alteration is located in exon 6 (coding exon 5) of the TMEM45A gene. This alteration results from a G to A substitution at nucleotide position 800, causing the arginine (R) at amino acid position 267 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
