The c.1058G>A (p.R353H) alteration is located in exon 10 (coding exon 10) of the TM6SF2 gene. This alteration results from a G to A substitution at nucleotide position 1058, causing the arginine (R) at amino acid position 353 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
