The c.1724A>G (p.D575G) alteration is located in exon 16 (coding exon 16) of the LRRC7 gene. This alteration results from a A to G substitution at nucleotide position 1724, causing the aspartic acid (D) at amino acid position 575 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
