Genes affected
ABCA13 (HGNC:14638): (ATP binding cassette subfamily A member 13) In human, the ATP-binding cassette (ABC) family of transmembrane transporters has at least 48 genes and 7 gene subfamilies. This gene is a member of ABC gene subfamily A (ABCA). Genes within the ABCA family typically encode several thousand amino acids. Like other ABC transmembrane transporter proteins, this protein has 12 or more transmembrane alpha-helix domains that likely arrange to form a single central chamber with multiple substrate binding sites. It is also predicted to have two large extracellular domains and two nucleotide binding domains as is typical for ABCA proteins. Alternative splice variants have been described but their biological validity has not been demonstrated.[provided by RefSeq, Mar 2009]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.009026817 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5.1, offset of 4, new splice context is: cttGTaagg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 7-48387961-T-C is Pathogenic according to our data. Variant chr7-48387961-T-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 210065.Status of the report is criteria_provided_single_submitter, 1 stars.
