The c.598C>T (p.R200W) alteration is located in exon 4 (coding exon 4) of the KLHDC10 gene. This alteration results from a C to T substitution at nucleotide position 598, causing the arginine (R) at amino acid position 200 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
