Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2022The c.1409G>T (p.S470I) alteration is located in exon 9 (coding exon 9) of the RFTN2 gene. This alteration results from a G to T substitution at nucleotide position 1409, causing the serine (S) at amino acid position 470 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
