Molecular Characterisation of Treacher Collins Syndrome in a South African Cohort: Novel Disease‐Causing Variants in TCOF1 and POLR1D

Treacher Collins syndrome (TCS) is a rare craniofacial disorder characterised by variable expressivity. It is caused by pathogenic variants in the TCOF1, POLR1D, POLR1C, or POLR1B genes. Common clinical features include hypoplasia of the zygomatic complex and mandible, downward‐slanting palpebral fissures, lower eyelid...

Copy number variant analysis by exome sequencing is an effective approach to optimize diagnostic yield for developmental disorders-the DDD-Africa study.

The addition of CNV analysis to the ES analysis pipeline resulted in an 8.1% increase in diagnostic yield in the DDD-Africa cohort without additional laboratory cost, which is likely to reduce analytical cost and is suitable for low- and middle-income countries where funding and resources for genomic medicine initiativ...
