The c.240C>A (p.D80E) alteration is located in exon 1 (coding exon 1) of the FGD5 gene. This alteration results from a C to A substitution at nucleotide position 240, causing the aspartic acid (D) at amino acid position 80 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
