The c.800A>G (p.Q267R) alteration is located in exon 2 (coding exon 2) of the TMEM132C gene. This alteration results from a A to G substitution at nucleotide position 800, causing the glutamine (Q) at amino acid position 267 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
