The c.2617C>T (p.H873Y) alteration is located in exon 4 (coding exon 4) of the FGD6 gene. This alteration results from a C to T substitution at nucleotide position 2617, causing the histidine (H) at amino acid position 873 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
