Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.529G>A (p.V177M) alteration is located in exon 5 (coding exon 4) of the HDHD2 gene. This alteration results from a G to A substitution at nucleotide position 529, causing the valine (V) at amino acid position 177 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
