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.3014T>C (p.V1005A) alteration is located in exon 25 (coding exon 24) of the ATP8B4 gene. This alteration results from a T to C substitution at nucleotide position 3014, causing the valine (V) at amino acid position 1005 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
