Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 15, 2021The c.518A>G (p.N173S) alteration is located in exon 6 (coding exon 6) of the RTFDC1 gene. This alteration results from a A to G substitution at nucleotide position 518, causing the asparagine (N) at amino acid position 173 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
