Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong
The NM_001042413.2(GLIS3):c.1154G>T(p.Gly385Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000288 in 1,574,282 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G385S) has been classified as Uncertain significance.

Neonatal diabetes mellitus with congenital hypothyroidism Uncertain:3
Potent mutations in GLIS3 predisposes to neonatal diabetes mellitus with an extra pancreatic manifestation of hypothyroidism. It also predisposes to early onset diabetes in adults.However no sufficient evidence is found to ascertain the role of this particular variant rs200959196, yet. -
The GLIS3 c.1154G>T (p.Gly385Val) was identified. This variant, to our knowledge, has not been reported in the medical literature. This variant has been reported in the ClinVar database as a variant of uncertain significance by two submitters (ClinVar ID: 549531). Computational predictors suggest that the variant does not impact GLIS3 function. Due to limited information, and based on the ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time. -

ACMG Criteria:BP4 (9 predictors) -
not provided Uncertain:1
This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 230 of the GLIS3 protein (p.Gly230Val). This variant is present in population databases (rs200959196, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with GLIS3-related conditions. ClinVar contains an entry for this variant (Variation ID: 549531). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
