Collection Method:clinical testing

The c.209A>T (p.E70V) alteration is located in exon 2 (coding exon 2) of the KRT222 gene. This alteration results from a A to T substitution at nucleotide position 209, causing the glutamic acid (E) at amino acid position 70 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
