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]

BPHL (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.904

The c.341T>C (p.F114S) alteration is located in exon 3 (coding exon 3) of the BPHL gene. This alteration results from a T to C substitution at nucleotide position 341, causing the phenylalanine (F) at amino acid position 114 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
