Genes affected
ABCB8 (HGNC:49): (ATP binding cassette subfamily B member 8) This nuclear gene encodes a multi-pass membrane protein that is targeted to the mitochondrial inner membrane. The encoded protein is an ATP-dependent transporter that may mediate the passage of organic and inorganic molecules out of the mitochondria. Loss of function of the related gene in mouse results in a disruption of iron homeostasis between the mitochondria and cytosol. Alternative splicing results in multiple transcript variants.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.827G>A (p.R276H) alteration is located in exon 6 (coding exon 6) of the ABCB8 gene. This alteration results from a G to A substitution at nucleotide position 827, causing the arginine (R) at amino acid position 276 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
