RCPS EIF4A3

Richieri Costa-Pereira syndrome is characterized by short stature, Robin sequence, cleft mandible, pre/postaxial hand anomalies (including hypoplastic thumbs), and clubfoot. It has been described in 14 Brazilian families and in one unrelated French patient. Prominent low set ears and a highly arched palate were also observed. Transmission is autosomal recessive¹.

Prevalence

49 cases as of Nov 2023². Found in Brazilian families and one unrelated French patient¹.

Details

Complex repeat of 18-20 nucleotides expands to cause diease: disease is found in individuals with 14-16 repeats³, while controls have typically 3-12 repeats with as low as 1 repeat^4,5. Significance of intermediate alleles is unknown⁶.

Mechanism

LoF

LoF from a hypomorphic allele³.

Year

2014³; syndrome described in 1992⁷
