Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2021The c.7C>T (p.R3W) alteration is located in exon 1 (coding exon 1) of the HEPHL1 gene. This alteration results from a C to T substitution at nucleotide position 7, causing the arginine (R) at amino acid position 3 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
