Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 31, 2024The c.412G>T (p.A138S) alteration is located in exon 4 (coding exon 4) of the BPIFB3 gene. This alteration results from a G to T substitution at nucleotide position 412, causing the alanine (A) at amino acid position 138 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
