Genes affected
ABCG4 (HGNC:13884): (ATP binding cassette subfamily G member 4) The protein encoded by this gene is a member of the ATP-binding cassette (ABC) transporter superfamily. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). The encoded protein is a member of the White subfamily and plays an important role in cellular cholesterol homeostasis. This protein functions as either a homodimer or as a heterodimer with another ABC subfamily protein such as ABCG1. [provided by RefSeq, Jan 2017]

The c.14C>T (p.A5V) alteration is located in exon 2 (coding exon 1) of the ABCG4 gene. This alteration results from a C to T substitution at nucleotide position 14, causing the alanine (A) at amino acid position 5 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
