Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 10, 2024The c.1338G>T (p.E446D) alteration is located in exon 10 (coding exon 10) of the EXD1 gene. This alteration results from a G to T substitution at nucleotide position 1338, causing the glutamic acid (E) at amino acid position 446 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
