The c.1681G>A (p.V561I) alteration is located in exon 11 (coding exon 11) of the ADGRL4 gene. This alteration results from a G to A substitution at nucleotide position 1681, causing the valine (V) at amino acid position 561 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
