Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2024The c.1447A>G (p.K483E) alteration is located in exon 15 (coding exon 15) of the BPIFC gene. This alteration results from a A to G substitution at nucleotide position 1447, causing the lysine (K) at amino acid position 483 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
