Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 26, 2023The c.730G>A (p.V244M) alteration is located in exon 6 (coding exon 6) of the RFNG gene. This alteration results from a G to A substitution at nucleotide position 730, causing the valine (V) at amino acid position 244 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
