Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 11, 2023The c.414G>T (p.K138N) alteration is located in exon 5 (coding exon 5) of the PIFO gene. This alteration results from a G to T substitution at nucleotide position 414, causing the lysine (K) at amino acid position 138 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
