Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.959A>G (p.K320R) alteration is located in exon 11 (coding exon 11) of the TXK gene. This alteration results from a A to G substitution at nucleotide position 959, causing the lysine (K) at amino acid position 320 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
