Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.644C>T (p.T215M) alteration is located in exon 4 (coding exon 3) of the IFI44 gene. This alteration results from a C to T substitution at nucleotide position 644, causing the threonine (T) at amino acid position 215 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
