MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] NEPH1 is a member of the nephrin-like protein family, which includes NEPH2 (MIM 607761) and NEPH3 (MIM 607762). The cytoplasmic domains of these proteins interact with the C terminus of podocin (NPHS2; MIM 604766), and the genes are expressed in kidney podocytes, cells involved in ensuring size- and charge-selective ultrafiltration (Sellin et al., 2003 [PubMed 12424224]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Mice homozygous for a gene trap insertion exhibit postnatal lethality and are small and sickly. Glomerular and tubular defects in the kidney result in severe proteinuria. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to T transversion at position 2673 of the Kirrel transcript in exon 16 of 16 total exons. Multiple transcripts of the Kirrel gene are displayed on Ensembl and Vega. The mutated nucleotide causes a threonine to serine substitution at amino acid 771 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Kirrel gene encodes a two isoforms of a single-pass type I membrane protein that is located predominantly at the podocyte slit diaphragm of kidney glomeruli known as NEPH1, a member of the nephrin-like protein family. The cytoplasmic domains of these proteins interact with the the C-terminus of podocin, a protein that is crucial for establishing the glomerular filtration barrier. This protein plays a significant role in the normal development and function of the glomerular permeability, and is a signaling protein that needs the presence of TEC kinases to fully trans-activate the transcription factor AP-1. The standard isoform contains 789 amino acids with five Ig-like C2-type immunoglobulin domains in the extracellular region. Isoform 2 has a variant cytoplasmic region (Uniprot Q80W68). Mice homozygous for a gene trap insertion exhibit postnatal lethality and are small and sickly. Glomerular and tubular defects in the kidney result in severe proteinuria.

The T771S change is predicted to be benign by the PolyPhen program.
