Genes affected
ADAT3 (HGNC:25151): (adenosine deaminase tRNA specific 3) This gene encodes a subunit of a tRNA-specific adenosine deaminase. This heterodimeric enzyme converts adenosine to inosine in the tRNA anticodon. A mutation in this gene causes a syndrome characterized by intellectual disability and strabismus. This gene shares its 5' exon with the overlapping gene, secretory carrier membrane protein 4 (Gene ID: 113178). [provided by RefSeq, Jul 2016]
SCAMP4 (HGNC:30385): (secretory carrier membrane protein 4) Secretory carrier membrane proteins (SCAMPs) are widely distributed integral membrane proteins implicated in membrane trafficking. Most SCAMPs (e.g., SCAMP1; MIM 606911) have N-terminal cytoplasmic NPF (arg-pro-phe) repeats, 4 central transmembrane regions, and a short C-terminal cytoplasmic tail. These SCAMPs likely have a role in endocytosis that is mediated by their NPF repeats. Other SCAMPs, such as SCAMP4, lack the NPF repeats and are therefore unlikely to function in endocytosis (summary by Fernandez-Chacon and Sudhof, 2000 [PubMed 11050114]).[supplied by OMIM, Feb 2011]

The homozgous p.Val144Met variant was identified by our study in one individual with mental retardation. Of note, a first cousin who was noted to also have mental retardation was a carrier for this variant. The p.Val144Met variant is believed to be pathogenic based on numberous reports by other laboratories in the literature and databases. -

This variant is predicted to be damaging by in-silico missense prediction tools (SIFT and Polyphen2). The variant (also known as V128M in literature) was previously reported in patients with intellectual disability and considered as founder mutation in the Saudi Arabian population [PMID: 26842963, 23620220, 32214227]. Functional studies using cell lines derived from intellectual disability-affected individuals showed a severe reduction in tRNA deaminase activity [PMID: 31263000]. -

We detected the variant NM_138422.3(ADAT3): c.430G>A (p.Val144Met, rs730882213) in two female siblings with Mental retardation, autosomal recessive 36 using whole-exome sequencing. We validated the variant's status in the patients using Sanger sequencing and detected it in a heterozygous status in their parents. Multiple reports previously classified the variant NM_138422.3(ADAT3): c.430G>A (p.Val144Met, rs730882213) as pathogenic (Alazami et al., 2013; El-Hattab et al., 2016). -
