Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 25, 2023The c.1304C>T (p.T435I) alteration is located in exon 9 (coding exon 9) of the RFTN2 gene. This alteration results from a C to T substitution at nucleotide position 1304, causing the threonine (T) at amino acid position 435 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
