Variant 3-11017119-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 5P and 4B. PVS1_StrongPP5BS2

The NM_001348250.2(SLC6A1):c.-92-1G>A variant causes a splice acceptor, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000537 in 987,032 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 2/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely pathogenic (no stars).

Genes affected

SLC6A1 (HGNC:11042): (solute carrier family 6 member 1) The protein encoded by this gene is a gamma-aminobutyric acid (GABA) transporter that localizes to the plasma membrane. The encoded protein removes GABA from the synaptic cleft, restoring it to presynaptic terminals. [provided by RefSeq, Jan 2017]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.18277778 fraction of the gene. Cryptic splice site detected, with MaxEntScore 7, offset of 1, new splice context is: acccaccccgtcctcctaAGgtg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

PP5

Variant 3-11017119-G-A is Pathogenic according to our data. Variant chr3-11017119-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 3256734.Status of the report is no_assertion_criteria_provided, 0 stars.

BS2

High AC in GnomAd4 at 9 AD gene.
