Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2024The c.334A>G (p.T112A) alteration is located in exon 2 (coding exon 1) of the IFI44 gene. This alteration results from a A to G substitution at nucleotide position 334, causing the threonine (T) at amino acid position 112 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
