RCV004785046 | SCV005397504 | uncertain significance | Intellectual developmental disorder, autosomal dominant 63, with macrocephaly | 2024-04-09 | criteria provided, single submitter | clinical testing | This sequence variant is a single nucleotide substitution (C>A) at position 2344 of the coding sequence of the TRIO gene that results in a leucine to methionine amino acid change at residue 782 of the trio Rho guanine nucleotide exchange factor protein. This residue falls between the second and third Spectrin 3 repeats (UniProt). This novel variant is absent from ClinVar, the published literature, and the gnomAD population database (0 of approximately 282,00 alleles). Multiple bioinformatic tools predict that this amino acid change would be damaging, and the Leu782 residue at this position is highly conserved across the vertebrate species examined. Studies examining the functiol consequence of this variant have not been published, to our knowledge. At this time, there is insufficient evidence to determine if this variant is pathogenic or benign. Therefore, we consider this a variant of uncertain significance. ACMG Criteria: PM2, PP3 |
