The c.1009G>A (p.A337T) alteration is located in exon 8 (coding exon 8) of the ADGRA2 gene. This alteration results from a G to A substitution at nucleotide position 1009, causing the alanine (A) at amino acid position 337 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
