Feb 14, 2023

The c.1612A>G (p.I538V) alteration is located in exon 12 (coding exon 12) of the TM7SF3 gene. This alteration results from a A to G substitution at nucleotide position 1612, causing the isoleucine (I) at amino acid position 538 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
