The c.3928C>G (p.P1310A) alteration is located in exon 47 (coding exon 47) of the COL24A1 gene. This alteration results from a C to G substitution at nucleotide position 3928, causing the proline (P) at amino acid position 1310 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
