Collection Method: clinical testing

The c.1811G>A (p.R604Q) alteration is located in exon 9 (coding exon 8) of the LNX2 gene. This alteration results from a G to A substitution at nucleotide position 1811, causing the arginine (R) at amino acid position 604 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
