Intellectual disability syndromic and non-syndromic v0.3062 | ITFG2 |
Konstantinos Varvagiannis gene: ITFG2 was added gene: ITFG2 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: ITFG2 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: ITFG2 were set to 28397838; https://doi.org/10.1038/s41525-020-00150-z Phenotypes for gene: ITFG2 were set to Neurodevelopmental abnormality; Intellectual disability; Developmental regression; Ataxia Penetrance for gene: ITFG2 were set to Complete Review for gene: ITFG2 was set to AMBER Added comment: ITFG2 was suggested to be a candidate gene for autosomal recessive ID in the study by Harripaul et al (2018 - PMID: 28397838). The authors performed microarray and exome sequencing in 192 consanguineous families and identified a homozygous ITGF2 stopgain variant (NM_018463.3:c.472G>T / p.Glu158*) along with 3 additional variants segregating with ID within an investigated family (PK51). Cheema et al (2020 - https://doi.org/10.1038/s41525-020-00150-z) report briefly on a male, born to consanguineous parents presenting with NDD, seizures, regression and ataxia. There was a similarly affected female sibling. Evaluation of ROH revealed a homozygous ITFG2 nonsense variant [NM_018463.3:c.361C>T / p.(Gln121*)]. Families in this study were investigated by trio WES or WGS. Evaluation of data of the same lab revealed 3 additional unrelated subjects with overlapping phenotypes, notably NDD and ataxia. These individuals were - each - homozygous for pLoF variants [NM_018463.3:c.848-1G>A; NM_018463.3:c.704dupC, p.(Ala236fs), NM_018463.3:c.1000_1001delAT, p.(Ile334fs)]. As discussed in OMIM, ITFG2 encodes a subunit of the KICSTOR protein complex, having a role in regulating nutrient sensing by MTOR complex-1 (Wolfson et al 2017 - PMID : 28199306). Please consider inclusion in the ID panel with amber rating, pending further details. Sources: Literature |
