Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2023The c.790G>T (p.V264L) alteration is located in exon 6 (coding exon 5) of the TSTD2 gene. This alteration results from a G to T substitution at nucleotide position 790, causing the valine (V) at amino acid position 264 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
