The c.2309A>G (p.D770G) alteration is located in exon 19 (coding exon 19) of the LRRC7 gene. This alteration results from a A to G substitution at nucleotide position 2309, causing the aspartic acid (D) at amino acid position 770 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
