The c.1547A>G (p.Y516C) alteration is located in exon 11 (coding exon 11) of the ADGRL4 gene. This alteration results from a A to G substitution at nucleotide position 1547, causing the tyrosine (Y) at amino acid position 516 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
