The c.61A>T (p.N21Y) alteration is located in exon 2 (coding exon 1) of the IFI44L gene. This alteration results from a A to T substitution at nucleotide position 61, causing the asparagine (N) at amino acid position 21 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
