Collection Method:clinical testing

The c.305C>A (p.T102K) alteration is located in exon 3 (coding exon 2) of the APOL6 gene. This alteration results from a C to A substitution at nucleotide position 305, causing the threonine (T) at amino acid position 102 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
