Genes affected

ABCF2 (HGNC:71): (ATP binding cassette subfamily F member 2) 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. Alterations in this gene may be involved in cancer progression. Related pseudogenes have been identified on chromosomes 3 and 7. [provided by RefSeq, Mar 2019]

ABCF2-H2BK1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, ABCF2
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.916

The c.1752G>C (p.W584C) alteration is located in exon 15 (coding exon 14) of the ABCF2 gene. This alteration results from a G to C substitution at nucleotide position 1752, causing the tryptophan (W) at amino acid position 584 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
