The c.4508G>A (p.G1503E) alteration is located in exon 28 (coding exon 27) of the CFAP44 gene. This alteration results from a G to A substitution at nucleotide position 4508, causing the glycine (G) at amino acid position 1503 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
