Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.125C>T (p.A42V) alteration is located in exon 2 (coding exon 1) of the THUMPD3 gene. This alteration results from a C to T substitution at nucleotide position 125, causing the alanine (A) at amino acid position 42 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
