MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is a member of the cadherin superfamily. Family members encode integral membrane proteins that mediate calcium-dependent cell-cell adhesion. It plays an essential role in maintenance of normal retinal and cochlear function. Mutations in this gene result in hearing loss and Usher Syndrome Type IF (USH1F). Extensive alternative splicing resulting in multiple isoforms has been observed in the mouse ortholog. Similar alternatively spliced transcripts are inferred to occur in human, and additional variants are likely to occur. [provided by RefSeq, Dec 2008]
PHENOTYPE: Homozygotes for severe mutations exhibit circling, head-tossing, hyperactivity, impaired swimming and profound deafness. Mice have defects in cochlea and degeneration of hair cells, spiral ganglion cells and saccular macula. Females are poor mothers. [provided by MGI curators]

Phenotypic Description
Figure 1. The sphere mice exhibit head tilting and circling.

The sphere phenotype was identified among G3 mice of the pedigree R4585, some of which showed head tilting and circling (Figure 1).

Nature of Mutation

Figure 2. Linkage mapping of the vestibular phenotype using a recessive model of inheritance. Manhattan plot shows -log10 P values (Y-axis) plotted against the chromosome positions of 90 mutations (X-axis) identified in the G1 male of pedigree R4585. Binary phenotype data are shown for single locus linkage analysis without consideration of G2 dam identity. Horizontal pink and red lines represent thresholds of P = 0.05, and the threshold for P = 0.05 after applying Bonferroni correction, respectively.

Whole exome HiSeq sequencing of the G1 grandsire identified 90 mutations. Two G3 mice with the sphere phenotype and 13 unaffected mice from a single pedigree were genotyped at all mutation sites identified in the G1 grandsire. One mutation on chromosome 10 (in Pcdh15) was homozygous in both of the sphere mice and either homozygous (n = 1), heterozygous (n = 5), or wild-type (n = 7) in the unaffected mice (P = 0.015; recessive model of inheritance). The mutation in Pcdh15 was presumed to be causative because the sphere circling and head tilting phenotype mimics other known alleles of Pcdh15 (see MGI for a list of Pcdh15 alleles as well as the entries for mcduck, spaz, and squirm).

The Pcdh15 mutation is a C to T transition at base pair 74,624,284 (v38) on chromosome 10, or base pair 1,524,257 in the GenBank genomic region NC_000076 for the Pcdh15 gene. The Pcdh15 gene encodes multiple isoforms of the PCDH15 protein (2;7). Due to the complexity of the Pcdh15 genomic region and the presence of alternative exons, it is possible that sphere mice still express potentially functional Pcdh15 isoforms, but this possibility has not been tested. 

The mutation corresponds to residue 4,499 in the mRNA sequence NM_023115 (variant A) within exon 31 of 35 total exons.

Genomic numbering corresponds to NC_000076. The mutated nucleotide is indicated in red.  The mutation results in an arginine (R) to tryptophan (W) substitution at position 1,360 (R1360W) in the PCDH15 protein (CD1-1 precursor), and is strongly predicted by PolyPhen-2 to be damaging (score = 1.000).

Figure 3. Domain structures of Pcdh15 splice variants. PCDH15 isoforms consist of up to 11 extracellular cadherin (EC) repeats, one transmembrane domain and a variable cytoplasmic domain that contains a PDZ-binding motif (PBM).The four isoform classes are defined based upon the cytoplasmic tail variation or the absence of the tail. The isoforms CD1, CD2, and CD3 are full length and contain a cytoplasmic tail encoded by 35, 38, and 39 exons, respectively. Isoform S1 is predicted to be secreted, contains only 10 EC repeats and lacks a cytoplasmic tail. The sphere mutation results in an arginine (R) to tryptophan (W) substitution at position 1,360 (R1360W) . Image is interactive. Other mutations found in the protein are noted in red. Click on each allele for more information.

The mouse Pcdh15 gene encodes a protein that belongs to the protocadherin protein family (Figure 3). Protocadherins are atypical members of the large cadherin (calcium-dependent cell-cell adhesion proteins (1)) superfamily of transmembrane proteins that are defined by the presence of a variable number of extracellular cadherin domains known as EC repeats (2;3).

The Pcdh15 gene encodes multiple isoforms of the PCDH15 protein; exon 1 is non-coding (4;5). The amino acids of each isoform are unique from each other, but each isoform contains a signal sequence, a unique extracellular region, and a cytoplasmic domain (4;6). The A isoform has 11 cadherin repeats, 1 transmembrane domain and a 542 amino acid cytoplasmic domain (CD1) that contains 2 proline-rich regions and the C-terminal motif STSL, which is a type 1 PDZ (for postsynaptic density 95/Discs large/zona occludens-1)-binding consensus sequence (4;5;7;8).

The sphere mutation results in an arginine (R) to tryptophan (W) substitution at position 1,360 (R1360W). Residue 1,360 is within an undefined region between the last EC repeat and the transmembrane domain.

Please see the record squirm for information about Pcdh15.

Putative Mechanism

Hearing and balance both depend on the function of hair cells of the inner ear.  The hair cells of the inner ear are mechanosensors that perceive sound, head movement, and gravity (9).  The hair bundle present in hair cells is composed of numerous stereocilia that develop from microvilli and have a stiff core of parallel actin filaments anchored in the cuticular plate, a meshwork of horizontal actin filaments beneath the apical cell membrane. The stereocilia are connected to each other by numerous filaments, including tip links, horizontal top connectors, shaft connectors, transient lateral links and ankle links. The tip link is composed of Pcdh15 and Cdh23 and is two intertwined strands; Pcdh15 localizes to the lower end of the tip link while Cdh23 is localized to the upper end (10;11). In the retina, the USH proteins colocalize in the synaptic layer of the OPL (12-14), as well as in the ciliary region between the outer and inner segments, particularly in the connecting cilium and the calycal processes (13;14).  PCDH15 colocalizes with harmonin, myosin VIIa, and CDH23 at the synaptic terminals of photoreceptor cells in the retina.

Human mutations that are predicted to truncate PCDH15 in the extracellular domain typically cause Usher syndrome (USH; OMIM: #602083) (7;8), whereas missense mutations are commonly associated with non-syndromic deafness (DFNB23; OMIM #609533). USH syndrome is the most common type of deaf-blindness in humans. USH can be associated with vestibular dysfunction and balance problems, reduced odor identification, reduced sperm motility, mental deficiency, cerebral atrophy, and ataxia (13;14).

The sphere phenotype mimics that of the Ames waltzer mouse model (Pcdh15av; av; MGI:1856467); homozygous Ames waltzer mice are characterized by circling, head-tossing, hyperactivity, impaired swimming and profound deafness due to defects in the cochlea and degeneration of hair cells, spiral ganglion cells and saccular macula (5;10). In a second Pcdh15 mutant mouse model, Pcdh15av-3J (MGI:1856394), a spontaneous single-base insertion after base pair 4,521 in Pcdh15, was identified (5;15). The mutation results in a frameshift and a premature stop codon; the truncated protein lacks the cytoplasmic domain (5). The Pcdh15av-3J mouse exhibited circling, difficulty swimming, and deafness due to outer hair cell degeneration, disorganized reticular lamina, absent apical (lateral or tip) links, dissociated kinocilia from the stereociliary bundles, and distorted and irregular outer hair cell bundles within the organ of Corti (15-18). The findings from the Pcdh15av-3J mouse indicate that an intact cytoplasmic domain is necessary for the function of PCDH15 in hearing and vestibular function.
