The c.437A>G (p.Q146R) alteration is located in exon 4 (coding exon 4) of the PHACTR2 gene. This alteration results from a A to G substitution at nucleotide position 437, causing the glutamine (Q) at amino acid position 146 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
