May 24, 2024

The c.67G>C (p.E23Q) alteration is located in exon 2 (coding exon 1) of the LRRC23 gene. This alteration results from a G to C substitution at nucleotide position 67, causing the glutamic acid (E) at amino acid position 23 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
