The c.1199A>G (p.N400S) alteration is located in exon 13 (coding exon 13) of the HSD17B4 gene. This alteration results from a A to G substitution at nucleotide position 1199, causing the asparagine (N) at amino acid position 400 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
