Collection Method: clinical testing

The c.620A>C (p.Y207S) alteration is located in exon 5 (coding exon 5) of the PCOLCE2 gene. This alteration results from a A to C substitution at nucleotide position 620, causing the tyrosine (Y) at amino acid position 207 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
