Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2024The c.1274A>G (p.K425R) 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 1274, causing the lysine (K) at amino acid position 425 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
