Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.434C>G (p.A145G) alteration is located in exon 5 (coding exon 5) of the PIFO gene. This alteration results from a C to G substitution at nucleotide position 434, causing the alanine (A) at amino acid position 145 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
