Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.1471G>A (p.A491T) alteration is located in exon 14 (coding exon 14) of the TXK gene. This alteration results from a G to A substitution at nucleotide position 1471, causing the alanine (A) at amino acid position 491 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
