Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 18, 2021The c.1739G>A (p.R580K) alteration is located in exon 8 (coding exon 7) of the LRRIQ3 gene. This alteration results from a G to A substitution at nucleotide position 1739, causing the arginine (R) at amino acid position 580 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
