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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 13, 2022The c.3362G>A (p.R1121H) alteration is located in exon 28 (coding exon 27) of the ATP8B4 gene. This alteration results from a G to A substitution at nucleotide position 3362, causing the arginine (R) at amino acid position 1121 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
