Carrier screening in the reproductive setting—Are there medical implications for the heterozygote?—A guide for clinicians

Pregnancy, Volume 2, Issue 3, May 2026.
Abstract Carrier screening for genetic conditions performed preconception or during pregnancy allows identification of fetal risk for inherited autosomal recessive and X‐linked conditions. The goal is to identify at‐risk patients/couples and offer them reproductive options such as preimplantation genetic diagnosis, prenatal testing, or targeted newborn

Genetic polymorphism in esr2 and risk of tooth agenesis

Rio de Janeiro Dental Journal (Revista Científica do CRO-RJ), 2019
Introduction: Tooth agenesis (TA) is the congenital absence of teeth. Several studies have proposed a strong genetic background for this condition. Aim: The present cross-sectional study aimed to evaluate whether genetic polymorphisms in the genes that code for estrogen receptors (ESR1 and ESR2) are associated with the presence of isolated TA in a ...

Novel frameshift variant of WNT10A in a Japanese patient with hypodontia

Human Genome Variation
Congenital tooth agenesis is caused by the impairment of crucial genes related to tooth development, such as Wnt signaling pathway genes. Here, we investigated the genetic causes of sporadic congenital tooth agenesis. Exome sequencing, followed by Sanger

Is Third-Molar Agenesis Related to the Incidence of Other Missing Teeth?

Turkish Journal of Orthodontics, 2014
Objective:The aim of this study was to investigate whether third-molar agenesis is related to agenesis of other missing teeth (incisor-premolar hypodontia [IPH]).Materials and Method:A sample of 94 Turkish patients with agenesis of upper lateral incisors

Exploring the Association Between Third Molar Agenesis and Carabelli Traits: A Cross-Sectional Study

Dentistry Journal
Background/Objectives: Dental agenesis is the congenital absence of at least one tooth and has been associated with several other developmental dental conditions, such as morphological dental alterations and Carabelli trait.

Third molar agenesis among children and youths from three major races of Malaysians

Journal of Dental Sciences, 2012
Background/purpose: Third molar (M3) agenesis is linked to the evolution and growth of the human jaw, as it is the last tooth to develop in the human dentition.
