The c.682G>A (p.A228T) alteration is located in exon 1 (coding exon 1) of the LRRIQ4 gene. This alteration results from a G to A substitution at nucleotide position 682, causing the alanine (A) at amino acid position 228 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
