Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 05, 2024The c.156G>C (p.E52D) alteration is located in exon 3 (coding exon 2) of the HEXDC gene. This alteration results from a G to C substitution at nucleotide position 156, causing the glutamic acid (E) at amino acid position 52 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
