The c.755A>G (p.Q252R) alteration is located in exon 3 (coding exon 3) of the TMEM151B gene. This alteration results from a A to G substitution at nucleotide position 755, causing the glutamine (Q) at amino acid position 252 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
