Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 17, 2024The c.985G>A (p.V329I) alteration is located in exon 2 (coding exon 1) of the VRTN gene. This alteration results from a G to A substitution at nucleotide position 985, causing the valine (V) at amino acid position 329 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
