May 08, 2023

The c.745G>T (p.D249Y) alteration is located in exon 7 (coding exon 7) of the TM7SF2 gene. This alteration results from a G to T substitution at nucleotide position 745, causing the aspartic acid (D) at amino acid position 249 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
