Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.203A>C (p.K68T) alteration is located in exon 2 (coding exon 2) of the TDRP gene. This alteration results from a A to C substitution at nucleotide position 203, causing the lysine (K) at amino acid position 68 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
