Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2022The c.287T>C (p.V96A) alteration is located in exon 3 (coding exon 2) of the THUMPD3 gene. This alteration results from a T to C substitution at nucleotide position 287, causing the valine (V) at amino acid position 96 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
