Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 05, 2024The c.369T>G (p.C123W) alteration is located in exon 1 (coding exon 1) of the IFNA13 gene. This alteration results from a T to G substitution at nucleotide position 369, causing the cysteine (C) at amino acid position 123 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
