Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.932C>G (p.S311C) alteration is located in exon 6 (coding exon 5) of the IFI44L gene. This alteration results from a C to G substitution at nucleotide position 932, causing the serine (S) at amino acid position 311 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
