French national reference center for genetic deafness (RCGD)
Deafness is the most frequent form of sensorial defect; it is reported to impair 1 children over 1000 at birth; 1 over 700 before adult age and an important percentage of the adult population. Although deafness is not rare, it gathers an important set of genetic rare diseases. It is estimated that 80% of infant hearing loss have genetic origins. Concerning hearing loss in adult population, the genetic part is yet to be determined but will for sure be important. To date, more than 100 genetic forms of isolated hearing loss are clearly identified and more than 500 syndromes (including deafness) have been described.

Genetic deafness explained to children
A video made by the reference center to explain genetic deafness to deaf children and their parents.
Eloquence of the deaf
First France deaf at birth lawyer, Virginie reveals her daily life as a "model disabled person", between exclusion and the struggle to adapt. A sensitive plunge into the world of the hearing-impaired.
Within the framework of the rare disease plan projects, the reference center for genetic deafness is attached to the SENSGENE rare diseases healthcare network (coordinated by Professor Hélène Dollfus, Strasbourg University hospital) and therefore carries out all the missions of the network in relation to genetic deafness. The reference center is also affiliated with the Rare craniofacial anomalies and ENT disorders European Reference Network (ERN).

On the occasion of its next annual conference, which will take place on 9 and 10 November 2022, ACFOS will address the theme of « Deafness and associated disorders: from diagnosis to support ». In this context, we wish to question professionals in contact with deaf children with associated disorders on their practices, their difficulties and their expectations.
Thank you in advance for taking a few minutes to complete the following questionnaire.
The results of the survey will be presented at the November conference.

The reference center for genetic deafness (RCGD) is unique in France. It has been created in 2000 by Dr Sandrine Marlin and accredited during the first french rare diseases national plan in 2004.
Located in Necker Hospital (dedicated to children), the center coordinates a national network composed by 2 constitutive sites : in La Pitié-Salpétrière (dedicated to adult) directed by Dr Isabelle Mosnier and in Lille directed by Dr Catherine Vincent Delorme (children and adult) ; and 20 competence centers displayed in France (metropolitan and overseas). The network regroups clinical geneticists, ENT, and molecular biologists.
Each year the RCGD of Necker’s hospital receives 700 different families. The patient care is assured by a team composed with a geneticist doctor, a genetic counselor, a clinical psychologist, a nurse and a secretary, working together with the ENT departments of Necker and La Pitié-Salpêtrière, leaders in deaf patient care in France. The center is located in medical genetic Department of Imagine institute in Necker Hospital.
The RCGD and its national network have defined a patient care permitting the diagnosis for deaf children, teenagers and young adults improving the transition from children to adult hospital.

The National Diagnostic and Care Protocols (NDCP or PNDS in French) are best practice guidelines for rare diseases. The objective of a PNDS is to explain to the professionals concerned the optimal diagnostic and therapeutic management and the care pathway for a patient suffering from a given rare disease.
As provided for in the 2011-2014 second national plan for rare diseases, they are developed by reference and competence centers for rare diseases using a method proposed by the Haute Autorité de Santé (HAS).
The PNDS include a « summary for the treating physician » section.
- 22q11 deletion (2016)
- Rasopathies (Noonan Syndrome and related) (2016)
- Pendred syndrome (2021)
- Heimler syndrome (2021)
- Ear aplasia (ongoing)
- Trisomy 21 (in progress)

CRESAM is a structure that pursues an original project at the service of children and adults suffering from double sensory deficiency.
The CNRHR Robert Laplane has a role of specific clinical expertise, transfer and development of competences, animation of specialized networks as well as formalization and diffusion of knowledge concerning the situations of rare handicap concerning deaf children.
For information on deafness, parents of deaf children and people with hearing loss have a national system consisting of a telephone platform (0812 040 040) and a website.
Acfos dedicates its action to knowledge and training about deafness, mainly congenital or acquired during childhood.
FISAF, the national federation for the inclusion of people with sensory disabilities and DYS disorders in France, created in 1925, recognized as being of public utility, federates 180 associations, establishments and services that welcome, train and accompany more than 16,000 people with sensory disabilities and DYS disorders with or without associated handicaps thanks to a network of 6,000 professionals representing more than 50 professions.

The 2021 International Usher info symposium is organized as a free digital event. It is open to scientists, patients, and their family. It is scheduled as follows (registration free but mandatory) :
- International Usher info scientific symposium : from October 6 to 8, 2021, every day from 3:00 pm to 6:30 pm (official language: English)
The symposium is co-chaired by Prof. José-Alain Sahel and Prof. Christine Petit. It is an invitation to specialists in the field to meet and share recent scientific, therapeutic and technological advances associated with the sensory impairments of Usher syndrome. It will gather outstanding experts and actors (ENTs, ophthalmologists, residents, young scientists, students, patient associations) in the field of sensory disorders.
