MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a member of the Ig superfamily of cell adhesion molecules and is involved in neuronal differentiation. The encoded membrane-bound protein localizes to the cell surface, where it forms aggregates that repel neuronal processes of the same cell type. [provided by RefSeq, Sep 2016]
PHENOTYPE: Mice homozygous for a gene trapped allele exhibit impaired self-avoidance in multiple cell types in the retina. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to T transversion at position 2348 of the Dscaml1transcript in exon 10 of 33 total exons. Three transcripts of the Dscaml1 gene are displayed on Ensembl. The mutated nucleotide causes a histidine to leucine substitution at amino acid 783 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Dscaml1 gene encodes a 2111 amino acid protein that is predicted to contain 10 immunoglobin (Ig) and Ig-like domains as well as six fibronectin type 3 (FN3) domains (SMART). Mice homozygous for a gene trapped allele exhibit impaired self-avoidance in multiple cell types in the retina.

The H783L change occurs in the eighth Ig-like domain and is predicted to be probably damaging by the PolyPhenprogram.
