Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 12, 2024The c.1406G>A (p.G469D) alteration is located in exon 10 (coding exon 9) of the TSTD2 gene. This alteration results from a G to A substitution at nucleotide position 1406, causing the glycine (G) at amino acid position 469 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
