The c.673T>G (p.S225A) alteration is located in exon 6 (coding exon 6) of the SYNPR gene. This alteration results from a T to G substitution at nucleotide position 673, causing the serine (S) at amino acid position 225 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
