Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 29, 2023The c.419C>G (p.T140S) alteration is located in exon 2 (coding exon 1) of the IFI44 gene. This alteration results from a C to G substitution at nucleotide position 419, causing the threonine (T) at amino acid position 140 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
