Genes affected

ABCF3 (HGNC:72): (ATP binding cassette subfamily F member 3) This gene encodes a member of the ATP-binding cassette (ABC) transporter superfamily. ATP-binding cassette proteins transport various molecules across extra- and intracellular membranes. The protein encoded by this gene displays antiviral effect against flaviviruses. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2017]

The c.524C>T (p.S175F) alteration is located in exon 6 (coding exon 6) of the ABCF3 gene. This alteration results from a C to T substitution at nucleotide position 524, causing the serine (S) at amino acid position 175 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
