Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.1283G>A (p.R428Q) alteration is located in exon 11 (coding exon 11) of the NARFL gene. This alteration results from a G to A substitution at nucleotide position 1283, causing the arginine (R) at amino acid position 428 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
