Nature of Mutation
DNA sequencing using the SOLiD technique identified an A to C transversion at position 5052 of the Lrrc7 transcript, in exon 22 of 28 total exons. Two Lrrc7 transcripts are displayed on Ensembl. The mutated nucleotide causes an isoleucine to leucine substitution at amino acid 1255 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
Lrrc7 encodes the 1542 amino acid leucine-rich repeat-containing protein 7 (LAP1). The protein belongs to the LAP (LRR and PDZ) protein family, and contains 18 leucine-rich (LRR) repeats at amino acids 21-970 and a protein-interaction PDZ domain at amino acids 1398-1488. The protein is phosphorylated at multiple residues. LAP1 may be involved in the organization of synaptic cell-cell contacts. A 1490 amino acid isoform of the protein is displayed on Uniprot (Uniprot Q80TE7). 
 
The I1255L change is predicted to be benign by the PolyPhen program.
