Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.1945G>A (p.A649T) alteration is located in exon 12 (coding exon 12) of the DNER gene. This alteration results from a G to A substitution at nucleotide position 1945, causing the alanine (A) at amino acid position 649 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
