Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2022The c.109G>A (p.V37I) alteration is located in exon 2 (coding exon 1) of the TXNL4B gene. This alteration results from a G to A substitution at nucleotide position 109, causing the valine (V) at amino acid position 37 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
