dbSNP rs1311019867: DLK2:p.Ala284Gly (chr6-43450840-G-C) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_023932.4(DLK2):c.851C>G(p.Ala284Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,848 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A284D) has been classified as Uncertain significance.

Genes affected

DLK2 (HGNC:21113): (delta like non-canonical Notch ligand 2) Predicted to enable Notch binding activity. Involved in negative regulation of Notch signaling pathway. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

DLK2 links:

ABCC10 (HGNC:52): (ATP binding cassette subfamily C member 10) The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, and White). This ABC full-transporter is a member of the MRP subfamily which is involved in multi-drug resistance. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Nov 2010]
