The c.1082T>G (p.M361R) alteration is located in exon 6 (coding exon 5) of the SCARA5 gene. This alteration results from a T to G substitution at nucleotide position 1082, causing the methionine (M) at amino acid position 361 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
