Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 17, 2023The c.222G>T (p.E74D) alteration is located in exon 4 (coding exon 3) of the PHRF1 gene. This alteration results from a G to T substitution at nucleotide position 222, causing the glutamic acid (E) at amino acid position 74 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
