Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.1246C>T (p.R416C) alteration is located in exon 12 (coding exon 12) of the BPIFC gene. This alteration results from a C to T substitution at nucleotide position 1246, causing the arginine (R) at amino acid position 416 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
