The c.1226C>T (p.A409V) alteration is located in exon 7 (coding exon 6) of the LRRIQ3 gene. This alteration results from a C to T substitution at nucleotide position 1226, causing the alanine (A) at amino acid position 409 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
