Genes affected

DLGAP2 (HGNC:2906): (DLG associated protein 2) The product of this gene is a membrane-associated protein that may play a role in synapse organization and signalling in neuronal cells. This gene is biallelically expressed in the brain, however, only the paternal allele is expressed in the testis (PMID:18055845). Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jun 2014]

The c.286T>C (p.C96R) alteration is located in exon 2 (coding exon 1) of the DLGAP2 gene. This alteration results from a T to C substitution at nucleotide position 286, causing the cysteine (C) at amino acid position 96 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
