Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2023The c.115A>G (p.T39A) alteration is located in exon 2 (coding exon 1) of the THUMPD3 gene. This alteration results from a A to G substitution at nucleotide position 115, causing the threonine (T) at amino acid position 39 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
