Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024The c.14G>A (p.R5H) alteration is located in exon 2 (coding exon 1) of the HDHD2 gene. This alteration results from a G to A substitution at nucleotide position 14, causing the arginine (R) at amino acid position 5 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
