The c.974C>G (p.T325R) alteration is located in exon 8 (coding exon 8) of the DCBLD1 gene. This alteration results from a C to G substitution at nucleotide position 974, causing the threonine (T) at amino acid position 325 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
