GeneDx	RCV000254727	SCV000321383	pathogenic	not provided	2017-05-05	criteria provided, single submitter	clinical testing	The V144M variant in the ADAT3 gene has been reported previously in the homozygous state as V128M, due to the use of alternative nomenclature, in several individuals with intellectual disability from unrelated, consanguineous families (Alazami et al., 2013; El-Hattab et al., 2016; Shaheen et al., 2016). Although adequate data is not available in large population cohorts to assess the frequency of this variant in publicly available databases, this variant is considered a Saudi Arabian founder mutation (Alazami et al., 2013; El-Hattab et al., 2016; Shaheen et al., 2016). The V144M variant is a conservative amino acid substitution which occurs at a position where amino acids with similar properties to Valine are tolerated across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret V144M as a pathogenic variant.
Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard	RCV000162122	SCV000786718	pathogenic	Intellectual disability-strabismus syndrome		criteria provided, single submitter	research	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.

Department of Biochemistry, Faculty of Medicine, University of Khartoum	RCV000162122	SCV001547514	pathogenic	Intellectual disability-strabismus syndrome	2021-03-25	criteria provided, single submitter	research	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).
