Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 02, 2024The c.1797A>T (p.E599D) alteration is located in exon 9 (coding exon 7) of the HDX gene. This alteration results from a A to T substitution at nucleotide position 1797, causing the glutamic acid (E) at amino acid position 599 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
