Variant summary
Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM1PM2PP3_Moderate
The NM_006005.3(WFS1):c.1079G>A(p.Cys360Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000203 in 1,613,958 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★).

not provided Uncertain:3
Reported as a variant of uncertain significance in a patient referred for whole exome sequencing who was also compound heterozygous for another variant of uncertain significance in WFS1 (PMID: 27959697); patient clinical information not provided; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 26435059, 31264968, 27959697) -

This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 360 of the WFS1 protein (p.Cys360Tyr). This variant is present in population databases (rs147157374, gnomAD 0.02%). This missense change has been observed in individual(s) with multiple congenital anomalies or with type 1 diabetes (PMID: 27959697, 31264968). ClinVar contains an entry for this variant (Variation ID: 374398). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt WFS1 protein function with a positive predictive value of 95%. 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. -

Our laboratory reported dual molecular diagnoses in ACTG1 (NM_001199954.1, c.118C>T) and WFS1 (NM_001145853.1, c.2191A>G and c.1079G>A in trans) in one individual with reported features of delayed motor milestones, delayed speech, mild intellectual disability, congenital bilateral sensorineural hearing loss, dysmorphic features and eye anomalies (strabismus, possible cortical visual impairment). Brain MRI showed dysplastic corpus callosum and possible intracranial lipoma. Additionally, this variant was seen once in our laboratory in trans with another missense variant (c.2452C>T) in a 22-year-old male with muscle weakness, obesity and type II diabetes, hypertension, fatigue and fibromyalgia, primary hypothyroidism, thymic hyperplasia, short stature, and nonalcoholic steatohepatitis -
