Collection Method: clinical testing

The c.1564G>T (p.V522F) alteration is located in exon 2 (coding exon 1) of the LRRC4C gene. This alteration results from a G to T substitution at nucleotide position 1564, causing the valine (V) at amino acid position 522 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
