Associated with MEHMO syndrome in OMIM #300148 (XLR)
PMID: 30878599 - Gregory et al 2019 - X-chromosome exome sequencing identified a missense variant in EIF2S3 (p.Pro432Ser) in 3 related males with normal head circumferences and mild learning difficulties, hypopituitarism (GH and TSH deficiencies), and an unusual form of glucose dysregulation. The authors state this is the first time this combination of phenotypes has been reported in the literature.
Several other studies (PMID: 23063529,PMID: 27333055, PMID: 28055140) report the more severe MEHMO syndrome phenotype with severe learning difficulties, all in males. Heterozygous females are unaffected.
In PMID: 27333055 (Moortgat et al 2016) the growth hormone deficiency is noted in 2 related males, but for 1 it is reported that the pituitary gland and stalk were normal (not mentioned for the other). In PMID: 28055140 (Skopkova et al 2017) panhypopituitarism and partial hypopituitarism are noted as a clinical feature in two unrelated Slovakian patients (both with the same p.Ile465Serfs*4 variant).Created: 16 Sep 2022, 9:44 p.m. | Last Modified: 16 Sep 2022, 9:44 p.m.
