Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024The c.1176G>C (p.K392N) alteration is located in exon 8 (coding exon 8) of the RFTN2 gene. This alteration results from a G to C substitution at nucleotide position 1176, causing the lysine (K) at amino acid position 392 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
