Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.1024G>A (p.V342I) alteration is located in exon 6 (coding exon 6) of the RFTN2 gene. This alteration results from a G to A substitution at nucleotide position 1024, causing the valine (V) at amino acid position 342 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
