Dec 04, 2023

The c.301C>T (p.R101W) alteration is located in exon 3 (coding exon 2) of the BTNL9 gene. This alteration results from a C to T substitution at nucleotide position 301, causing the arginine (R) at amino acid position 101 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
