The c.1487G>T (p.C496F) alteration is located in exon 4 (coding exon 3) of the KLHL33 gene. This alteration results from a G to T substitution at nucleotide position 1487, causing the cysteine (C) at amino acid position 496 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
