Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 05, 2024The c.670A>G (p.I224V) alteration is located in exon 8 (coding exon 8) of the TXK gene. This alteration results from a A to G substitution at nucleotide position 670, causing the isoleucine (I) at amino acid position 224 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
