Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2023The c.5A>G (p.D2G) alteration is located in exon 1 (coding exon 1) of the TM6SF2 gene. This alteration results from a A to G substitution at nucleotide position 5, causing the aspartic acid (D) at amino acid position 2 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
