Genes affected

BPHL (HGNC:1094): (biphenyl hydrolase like) This gene encodes a member of the serine protease family of hydrolytic enzymes which contain a serine in their active site. The encoded protein may play a role in activation of the antiviral prodrug valacyclovir. Alternatively spliced transcript variants have been described.[provided by RefSeq, Jan 2009]

The c.75C>A (p.H25Q) alteration is located in exon 1 (coding exon 1) of the BPHL gene. This alteration results from a C to A substitution at nucleotide position 75, causing the histidine (H) at amino acid position 25 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
