Collection Method: clinical testing

The c.305C>T (p.A102V) alteration is located in exon 4 (coding exon 4) of the MAGIX gene. This alteration results from a C to T substitution at nucleotide position 305, causing the alanine (A) at amino acid position 102 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
