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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2024The c.433C>T (p.H145Y) alteration is located in exon 6 (coding exon 5) of the ABCB5 gene. This alteration results from a C to T substitution at nucleotide position 433, causing the histidine (H) at amino acid position 145 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
