Collection Method: clinical testing

The c.238A>G (p.K80E) alteration is located in exon 1 (coding exon 1) of the LRRIQ4 gene. This alteration results from a A to G substitution at nucleotide position 238, causing the lysine (K) at amino acid position 80 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
