Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2024The c.1289G>T (p.C430F) alteration is located in exon 5 (coding exon 3) of the HDX gene. This alteration results from a G to T substitution at nucleotide position 1289, causing the cysteine (C) at amino acid position 430 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
