Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2023The c.1364A>G (p.D455G) alteration is located in exon 6 (coding exon 4) of the HDX gene. This alteration results from a A to G substitution at nucleotide position 1364, causing the aspartic acid (D) at amino acid position 455 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
