Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 20, 2023The c.1492A>G (p.R498G) alteration is located in exon 7 (coding exon 6) of the LRRIQ3 gene. This alteration results from a A to G substitution at nucleotide position 1492, causing the arginine (R) at amino acid position 498 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
