Genes affected

ABCB5 (HGNC:46): (ATP binding cassette subfamily B member 5) ABCB5 belongs to the ATP-binding cassette (ABC) transporter superfamily of integral membrane proteins. These proteins participate in ATP-dependent transmembrane transport of structurally diverse molecules ranging from small ions, sugars, and peptides to more complex organic molecules (Chen et al., 2005 [PubMed 15760339]).[supplied by OMIM, Mar 2008]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0018613935).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.196 is higher than 0.05.
