Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.464G>A (p.S155N) alteration is located in exon 4 (coding exon 4) of the RFNG gene. This alteration results from a G to A substitution at nucleotide position 464, causing the serine (S) at amino acid position 155 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
