Genes affected

BLVRA (HGNC:1062): (biliverdin reductase A) The protein encoded by this gene belongs to the biliverdin reductase family, members of which catalyze the conversion of biliverdin to bilirubin in the presence of NADPH or NADH. Mutations in this gene are associated with hyperbiliverdinemia. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2011]

Ambry Genetics

Oct 12, 2021

The c.154G>A (p.D52N) alteration is located in exon 4 (coding exon 3) of the BLVRA gene. This alteration results from a G to A substitution at nucleotide position 154, causing the aspartic acid (D) at amino acid position 52 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
