What is the official name of the MYO1A gene?

The official name of this gene is “myosin IA.”

MYO1A is the gene's official symbol. The MYO1A gene is also known by other names, listed below.

What is the normal function of the MYO1A gene?

From NCBI Gene (

This gene encodes a member of the myosin superfamily. The protein represents an unconventional myosin; it should not be confused with the conventional skeletal muscle myosin-1 (MYH1). Unconventional myosins contain the basic domains characteristic of conventional myosins and are further distinguished from class members by their tail domains. They function as actin-based molecular motors. Mutations in this gene have been associated with autosomal dominant deafness. Alternatively spliced variants have been found for this gene.

From UniProt (MYO1A_HUMAN) (

Involved in directing the movement of organelles along actin filaments.

NOTE: UniProt (MYO1A_HUMAN) ( suggests using caution when interpreting this information.

How are changes in the MYO1A gene related to health conditions?

UniProt (MYO1A_HUMAN) ( provides the following information about the MYO1A gene's known or predicted involvement in human disease.

Deafness, autosomal dominant, 48 (DFNA48): A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. The disease is caused by mutations affecting the gene represented in this entry.

NCBI Gene ( lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the MYO1A gene.
  • Deafness, autosomal dominant 48 (, a catalog designed for genetics professionals and researchers, provides the following information about the MYO1A gene and its association with health conditions.

Where is the MYO1A gene located?

Cytogenetic Location: 12q13-q14

Molecular Location on chromosome 12: base pairs 57,028,517 to 57,050,765

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBI (

The MYO1A gene is located on the long (q) arm of chromosome 12 between positions 13 and 14.

The MYO1A gene is located on the long (q) arm of chromosome 12 between positions 13 and 14.

More precisely, the MYO1A gene is located from base pair 57,028,517 to base pair 57,050,765 on chromosome 12.
