The c.1633C>A (p.Q545K) alteration is located in exon 14 (coding exon 14) of the WDR46 gene. This alteration results from a C to A substitution at nucleotide position 1633, causing the glutamine (Q) at amino acid position 545 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
