Collection Method: clinical testing

The c.1894A>G (p.I632V) alteration is located in exon 14 (coding exon 14) of the ADGRL4 gene. This alteration results from a A to G substitution at nucleotide position 1894, causing the isoleucine (I) at amino acid position 632 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
