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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.939

Collection Method: clinical testing

The c.611G>T (p.R204L) alteration is located in exon 7 (coding exon 7) of the ABCF3 gene. This alteration results from a G to T substitution at nucleotide position 611, causing the arginine (R) at amino acid position 204 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
