The c.1271C>T (p.S424L) alteration is located in exon 11 (coding exon 11) of the VPS9D1 gene. This alteration results from a C to T substitution at nucleotide position 1271, causing the serine (S) at amino acid position 424 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
