May 08, 2024

The c.881G>T (p.R294L) alteration is located in exon 2 (coding exon 2) of the LRRC26 gene. This alteration results from a G to T substitution at nucleotide position 881, causing the arginine (R) at amino acid position 294 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
