Collection Method:clinical testing

The c.455C>G (p.A152G) alteration is located in exon 4 (coding exon 4) of the TM7SF2 gene. This alteration results from a C to G substitution at nucleotide position 455, causing the alanine (A) at amino acid position 152 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
