The c.784G>A (p.D262N) alteration is located in exon 10 (coding exon 8) of the CERS4 gene. This alteration results from a G to A substitution at nucleotide position 784, causing the aspartic acid (D) at amino acid position 262 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
