Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.797C>T (p.A266V) alteration is located in exon 6 (coding exon 6) of the TSR3 gene. This alteration results from a C to T substitution at nucleotide position 797, causing the alanine (A) at amino acid position 266 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
