The c.385G>T (p.V129L) alteration is located in exon 2 (coding exon 2) of the CD300C gene. This alteration results from a G to T substitution at nucleotide position 385, causing the valine (V) at amino acid position 129 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
