Autosomal dominant auditory neuropathy 1(NSDAN; AUNA1)

MedGen UID:
322984
Concept ID:
C1836743
Disease or Syndrome
Synonym: AUDITORY NEUROPATHY, NONSYNDROMIC DOMINANT
 
Gene (location): DIAPH3 (13q21.2)
 
Monarch Initiative: MONDO:0012196
OMIM®: 609129

Definition

Auditory neuropathy is a type of hearing loss defined by the preservation of cochlear outer hair cell function and abnormal or absent auditory brainstem responses. Auditory neuropathy may accompany peripheral neuropathy in a variety of dominant syndromes such as Charcot-Marie-Tooth disease (Satya-Murti et al., 1979) and has been observed in Friedreich ataxia (Satya-Murti et al., 1980). Auditory neuropathy unassociated with peripheral neuropathy most commonly occurs as a sporadic or recessive trait; see, for example, 601071. Genetic Heterogeneity of Autosomal Dominant Auditory Neuropathy See also AUNA2 (620384), caused by mutation in the ATP11A gene (605868) on chromosome 13q34, and AUNA3 (619832), caused by mutation in the TMEM43 gene (612048) on chromosome 3p25. [from OMIM]

Clinical features

From HPO
Sensorineural hearing loss disorder
MedGen UID:
9164
Concept ID:
C0018784
Disease or Syndrome
A type of hearing impairment in one or both ears related to an abnormal functionality of the cochlear nerve.
Absence of acoustic reflex
MedGen UID:
322049
Concept ID:
C1832834
Finding
Absence of the acoustic reflex, an involuntary contraction of the stapedius muscle that occurs in response to high-intensity sound stimuli.
Abnormal speech discrimination
MedGen UID:
322986
Concept ID:
C1836752
Finding
A type of hearing impairment prominently characterized by a difficulty in understanding speech, rather than an inability to hear speech. Poor speech discrimination is a very common symptom of high frequency hearing loss.
Abnormal auditory evoked potentials
MedGen UID:
141758
Concept ID:
C0522216
Finding
An abnormality of the auditory evoked potentials, which are used to trace the signal generated by a sound, from the cochlear nerve, through the lateral lemniscus, to the medial geniculate nucleus, and to the cortex.
