The c.383C>G (p.P128R) alteration is located in exon 3 (coding exon 1) of the TCF24 gene. This alteration results from a C to G substitution at nucleotide position 383, causing the proline (P) at amino acid position 128 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
