Laryngeal malformation in Richieri‐Costa Pereira syndrome: New findings

Abstract: Laryngeal structural anomalies were described in 13 cases of Richieri-Costa Pereira syndrome, and four previously reported cases were reviewed. The 17 individuals examined had the typical laryngeal anomalies and vocal disorders previously described. The new findings are the laryngeal microweb observed in three cases and arytenoid anteriorization movement observed in 14 cases.

“…A retrospective review of the clinical characteristics from 35 individuals reported in detail in the literature, previously to the uncovering of the molecular mechanism responsible for RCPS, was performed. [3][4][5][8][9][10][11][12][13][14][15][16][17] The main clinical findings obtained in this review were compared to those found in the cohort of this study. In the comparison between the 2 groups, Fisher's exact test, 2-tailed, was applied along with Bonferroni correction for 26 tests.…”

“…abnormalities have been described as been systematically associated with RCPS leading to a hoarse voice, including small round larynx, epiglottis hypoplasia/agenesis, microweb, hypertrophy of arytenoids and aryepiglottic folds, a fold in the posterior region of larynx and anteriorization movement of arytenoids. 5 The underlying molecular mechanism of this syndrome was revealed by our group by using homozygosity mapping and targeted sequencing. 6 We showed that most of the affected individuals presented a different pattern of a complex repeated motif consisting of 18 or 20 nucleotides in the 5 0 untranslated region (UTR) of EIF4A3, leading to an expansion of the number of the total repeats in the region in both alleles.…”

“…PRS is not a syndrome, but a sequence, with one abnormality causing the next. It is related to several other craniofacial malformations and may appear with a syndromic diagnosis, such as velocardiofacial, Stickler, craniofacial microsomia, RCPS and Treacher Collins Syndrome [19,24] .…”
