The c.405G>T (p.Q135H) alteration is located in exon 4 (coding exon 4) of the VPS9D1 gene. This alteration results from a G to T substitution at nucleotide position 405, causing the glutamine (Q) at amino acid position 135 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
