Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 11, 2023The c.1700G>A (p.R567Q) alteration is located in exon 5 (coding exon 4) of the LRRN4 gene. This alteration results from a G to A substitution at nucleotide position 1700, causing the arginine (R) at amino acid position 567 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
