Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2022The c.1963A>G (p.I655V) alteration is located in exon 17 (coding exon 17) of the RFWD2 gene. This alteration results from a A to G substitution at nucleotide position 1963, causing the isoleucine (I) at amino acid position 655 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
