Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.403A>G (p.I135V) alteration is located in exon 4 (coding exon 3) of the PHRF1 gene. This alteration results from a A to G substitution at nucleotide position 403, causing the isoleucine (I) at amino acid position 135 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
