The c.535G>A (p.V179I) alteration is located in exon 4 (coding exon 4) of the PCOLCE2 gene. This alteration results from a G to A substitution at nucleotide position 535, causing the valine (V) at amino acid position 179 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
