The c.115G>C (p.V39L) alteration is located in exon 5 (coding exon 1) of the KIAA0040 gene. This alteration results from a G to C substitution at nucleotide position 115, causing the valine (V) at amino acid position 39 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
