Oct 19, 2024

The c.19C>T (p.R7W) alteration is located in exon 1 (coding exon 1) of the CLEC2A gene. This alteration results from a C to T substitution at nucleotide position 19, causing the arginine (R) at amino acid position 7 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
