The c.57G>T (p.K19N) alteration is located in exon 1 (coding exon 1) of the C18orf8 gene. This alteration results from a G to T substitution at nucleotide position 57, causing the lysine (K) at amino acid position 19 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
