Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.739G>A (p.D247N) alteration is located in exon 8 (coding exon 8) of the PHTF2 gene. This alteration results from a G to A substitution at nucleotide position 739, causing the aspartic acid (D) at amino acid position 247 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
