Collection Method:clinical testing

The c.1595T>G (p.L532R) alteration is located in exon 7 (coding exon 6) of the LRRIQ3 gene. This alteration results from a T to G substitution at nucleotide position 1595, causing the leucine (L) at amino acid position 532 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
