Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.2140A>C (p.N714H) alteration is located in exon 19 (coding exon 19) of the RFWD2 gene. This alteration results from a A to C substitution at nucleotide position 2140, causing the asparagine (N) at amino acid position 714 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
