The c.451G>A (p.A151T) alteration is located in exon 1 (coding exon 1) of the FGD5 gene. This alteration results from a G to A substitution at nucleotide position 451, causing the alanine (A) at amino acid position 151 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
