not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.401C>A (p.A134E) alteration is located in exon 4 (coding exon 3) of the ODF3B gene. This alteration results from a C to A substitution at nucleotide position 401, causing the alanine (A) at amino acid position 134 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
