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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 11, 2024The c.119A>T (p.Y40F) alteration is located in exon 2 (coding exon 1) of the DLGAP2 gene. This alteration results from a A to T substitution at nucleotide position 119, causing the tyrosine (Y) at amino acid position 40 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
