Genes affected
BLMH (HGNC:1059): (bleomycin hydrolase) Bleomycin hydrolase (BMH) is a cytoplasmic cysteine peptidase that is highly conserved through evolution; however, the only known activity of the enzyme is metabolic inactivation of the glycopeptide bleomycin (BLM), an essential component of combination chemotherapy regimens for cancer. The protein contains the signature active site residues of the cysteine protease papain superfamily. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 14, 2022The c.994T>G (p.F332V) alteration is located in exon 9 (coding exon 9) of the BLMH gene. This alteration results from a T to G substitution at nucleotide position 994, causing the phenylalanine (F) at amino acid position 332 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
