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]

Ambry Genetics

Nov 10, 2022

The c.997A>T (p.I333F) alteration is located in exon 10 (coding exon 9) of the ABCB5 gene. This alteration results from a A to T substitution at nucleotide position 997, causing the isoleucine (I) at amino acid position 333 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
