The c.121A>C (p.T41P) alteration is located in exon 2 (coding exon 2) of the RIBC2 gene. This alteration results from a A to C substitution at nucleotide position 121, causing the threonine (T) at amino acid position 41 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
