Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2024The c.184G>A (p.V62I) alteration is located in exon 3 (coding exon 3) of the RTFDC1 gene. This alteration results from a G to A substitution at nucleotide position 184, causing the valine (V) at amino acid position 62 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
