Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 01, 2024The c.80T>C (p.V27A) alteration is located in exon 2 (coding exon 1) of the TXNL4B gene. This alteration results from a T to C substitution at nucleotide position 80, causing the valine (V) at amino acid position 27 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
