Aug 21, 2024

The c.2874G>T (p.K958N) alteration is located in exon 7 (coding exon 7) of the FGD6 gene. This alteration results from a G to T substitution at nucleotide position 2874, causing the lysine (K) at amino acid position 958 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
