| Intellectual disability v9.213 | TM2D3 | Achchuthan Shanmugasundram Classified gene: TM2D3 as Amber List (moderate evidence) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Intellectual disability v9.213 | TM2D3 | Achchuthan Shanmugasundram Added comment: Comment on list classification: There are four unrelated patients reported with severe global developmental delay. Hence, this gene can be promoted to green rating in the next GMS update. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Achchuthan Shanmugasundram changed review comment from: PMID:40449487 (2025) reported four unrelated individuals with overlapping clinical presentations, including microcephaly, severe global developmental delay with absent speech, autistic features, heart malformation, and dysmorphic facial features. Severe GDD was reported in all four patients. They were all identified with homozygous or compound heterozygous variants in TM2D3 gene via exome sequencing. There is also functional evidence available from SNB75 TM2D3-knockout cells as well as skin fibroblasts from affected individuals harboring the recurrent c.503G>A (p.Gly168Asp) allele. This gene has been associated with relevant phenotype in OMIM (MIM #621379, last accessed 02 January 2026) and Gene2Phenotype (with 'moderate' rating on DD panel), but not yet in ClinGen.
