Presentation
The consanguineous parents of the patient with a homozygous PLCB4 deletion each harboured the heterozygous deletion, but did not present the ACS phenotype, further suggesting that ACS is not caused by PLCB4 haploinsufficiency. [rug.nl]
It is caused by a developmental abnormality of the first and second pharyngeal arches and it is associated with great inter‐ and intra‐familial clinical variability, with some patients not presenting the typical phenotype of the syndrome. [ingentaconnect.com]
In addition to ACS, the patient harbouring a homozygous deletion presented with central apnoea, a phenotype that has not been previously reported in ACS patients. [iths.pure.elsevier.com]
He presented with QME, micrognathia,and prominent cheeks (Fig. 1Biiv). [documents.tips]

Pharyngitis
Affected structures arise from cranial neural crest cells, a population of cells in the embryo that reside in the pharyngeal arches and give rise to most of the bone, cartilage and connective tissue of the face. [bv.fapesp.br]
Auriculocondylar syndrome is a craniofacial disorder involving the first and second pharyngeal arches. [ctgt.net]
OMIM : 58 Auriculocondylar syndrome (ARCND) is a rare craniofacial disorder involving first and second pharyngeal arch derivatives and includes the key features of micrognathia, temporomandibular joint and condyle anomalies, microstomia, prominent cheeks [malacards.org]
It is caused by a developmental abnormality of the first and second pharyngeal arches and it is associated with great inter‐ and intra‐familial clinical variability, with some patients not presenting the typical phenotype of the syndrome. [ingentaconnect.com]
Both genes are predicted to function in the endothelin 1 (EDN1)-endothelin receptor type A (EDNRA) signalling pathway during the development of the pharyngeal arches. [ashg.org]

Treatment [ edit ] Treatment of this condyle usually requires a multi-team approach involving an oral surgeon, an orthodontist and a plastic surgeon. [5] A treatment usually involves some type of bone graft from one's own body to their low jaw. [en.wikipedia.org]

Prognosis: As PRS typically affects airway and feeding, success in managing these two aspects determines prognosis. [clinicaladvisor.com]

Etiology
Etiology and Pathogenesis Frequency This heterogeneous birth defect has a prevalence of approximately 1 per 8500 live births. The male-to-female ratio is 1:1, except in the X-linked form. Etiology Autosomal recessive inheritance is possible. [emedicine.medscape.com]

It was not associated with any soft tissue aberrations suggestive of any syndromic etiology. Aplasia is a rare anomaly and refers to the insufficient development of the mandibular condyle. True agenesis of the mandibular condyle is extremely rare. [jmedsoc.org]
It often appears during puberty affecting predominantly males. [6] The exact etiology of coronoid hyperplasia is not yet elucidated, but several theories have been postulated, including hyperactivity of the temporal muscle that causes reactive elongation [mjdrdypu.org]
CL/P is etiologically distinct from CP alone. First-degree relatives of patients with CL/P have an increased incidence of CL/P but not of CP alone. [ajnr.org]
