Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.419C>T (p.A140V) alteration is located in exon 3 (coding exon 3) of the TDRP gene. This alteration results from a C to T substitution at nucleotide position 419, causing the alanine (A) at amino acid position 140 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
