The c.895C>T (p.R299W) alteration is located in exon 8 (coding exon 8) of the VSTM4 gene. This alteration results from a C to T substitution at nucleotide position 895, causing the arginine (R) at amino acid position 299 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
