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]

Jan 26, 2022

The c.2963T>C (p.I988T) 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 2963, causing the isoleucine (I) at amino acid position 988 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
