The c.2966T>G (p.V989G) alteration is located in exon 33 (coding exon 32) of the COL28A1 gene. This alteration results from a T to G substitution at nucleotide position 2966, causing the valine (V) at amino acid position 989 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
