The c.640C>T (p.R214C) alteration is located in exon 1 (coding exon 1) of the LRRC14B gene. This alteration results from a C to T substitution at nucleotide position 640, causing the arginine (R) at amino acid position 214 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
