Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.476G>A (p.R159Q) alteration is located in exon 1 (coding exon 1) of the LVRN gene. This alteration results from a G to A substitution at nucleotide position 476, causing the arginine (R) at amino acid position 159 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
