Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2024The c.2048T>G (p.V683G) alteration is located in exon 1 (coding exon 1) of the AP5B1 gene. This alteration results from a T to G substitution at nucleotide position 2048, causing the valine (V) at amino acid position 683 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
