The c.491G>T (p.R164L) alteration is located in exon 3 (coding exon 3) of the LRRC73 gene. This alteration results from a G to T substitution at nucleotide position 491, causing the arginine (R) at amino acid position 164 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
