Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.632G>T (p.G211V) alteration is located in exon 5 (coding exon 5) of the RFNG gene. This alteration results from a G to T substitution at nucleotide position 632, causing the glycine (G) at amino acid position 211 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
