The c.183T>G (p.S61R) alteration is located in exon 2 (coding exon 2) of the DTYMK gene. This alteration results from a T to G substitution at nucleotide position 183, causing the serine (S) at amino acid position 61 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
