The c.5117T>C (p.I1706T) alteration is located in exon 60 (coding exon 60) of the COL24A1 gene. This alteration results from a T to C substitution at nucleotide position 5117, causing the isoleucine (I) at amino acid position 1706 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
