The c.995A>C (p.N332T) alteration is located in exon 2 (coding exon 2) of the KLHL42 gene. This alteration results from a A to C substitution at nucleotide position 995, causing the asparagine (N) at amino acid position 332 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
