Genes

MYOT Gene

Summary

Symbol

MYOT

Name

Myotilin

Description

Myotilin is a muscle protein that is a component of the Z disc.

Variants

Allele

P2

Type

Missense

DNA

The P2 variant of MYOT is chr14:37,818,823 A/G (EquCab3)

Protein

The P2 variant of MYOT is S232P based on the protein model XP_005599444.2.
Note that the protein model includes the P2 allele, rather than the reference allele represented by
 the genomic sequence of MYOT in EquCab3.0. Please see the P2 Allele of MYOT blog post.

Disease

Summary

The P2 variant of MYOT is proposed to be associated with exercise intolerance.

Other species

Human

Missense alleles of MYOT are associated with Myofibrillar Myopathy 3 (OMIM).

Mouse

A mouse knockout that entirely eliminates MYOT expression has no phenotype
 (PubMed ID), but engineered alleles that replicate human pathogenic variants produce a phenotype (PubMed ID).

Evolutionary conservation

Summary

The P2 missense allele replaces a serine in the serine-rich region with proline. This is a highly conserved position; proline is not seen in this position across a wide range of species.
