The c.192G>T (p.K64N) alteration is located in exon 5 (coding exon 1) of the KIAA0040 gene. This alteration results from a G to T substitution at nucleotide position 192, causing the lysine (K) at amino acid position 64 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
