Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2021The c.73G>A (p.D25N) alteration is located in exon 2 (coding exon 2) of the RTFDC1 gene. This alteration results from a G to A substitution at nucleotide position 73, causing the aspartic acid (D) at amino acid position 25 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
