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]

Collection Method:clinical testing

The c.787C>T (p.P263S) alteration is located in exon 6 (coding exon 5) of the DLK2 gene. This alteration results from a C to T substitution at nucleotide position 787, causing the proline (P) at amino acid position 263 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
