Genes affected

ATP8B4 (HGNC:13536): (ATPase phospholipid transporting 8B4 (putative)) This gene encodes a member of the cation transport ATPase (P-type) family and type IV subfamily. The encoded protein is involved in phospholipid transport in the cell membrane. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2013]

The c.3301C>T (p.R1101C) alteration is located in exon 28 (coding exon 27) of the ATP8B4 gene. This alteration results from a C to T substitution at nucleotide position 3301, causing the arginine (R) at amino acid position 1101 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
