Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.1103T>A (p.L368Q) alteration is located in exon 11 (coding exon 11) of the TXK gene. This alteration results from a T to A substitution at nucleotide position 1103, causing the leucine (L) at amino acid position 368 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
