Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2021The c.502T>C (p.Y168H) alteration is located in exon 5 (coding exon 4) of the HDHD2 gene. This alteration results from a T to C substitution at nucleotide position 502, causing the tyrosine (Y) at amino acid position 168 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
