Variant summary: ABCC8 c.3544C>T (p.Arg1182Trp) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251376 control chromosomes. c.3544C>T, also described as p.R1183W, has been reported in the literature in multiple individuals affected with Neonatal diabetes mellitus, and in at-least three cases, this variant arose de novo (Flanagan_2007, Ngoc_2021). Parents carrying this variant were also reported to be unaffected (Flanagan_2007). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 17446535, 34566892). ClinVar contains an entry for this variant (Variation ID: 210076. Pathogenic/Likely pathogenic). Based on the evidence outlined above, the variant was classified as pathogenic. (less)

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1182 of the ABCC8 protein (p.Arg1182Trp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of autosomal dominant neonatal diabetes mellitus (PMID: 17446535, 32893419). In at least one individual the variant was observed to be de novo. This variant is also known as R1183W. ClinVar contains an entry for this variant (Variation ID: 210076). 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 ABCC8 protein function with a positive predictive value of 95%. This variant disrupts the p.Arg1182 amino acid residue in ABCC8. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 16885549, 17446535, 22749773, 24622368). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. (less)

In a 35-year-old woman with maturity-onset diabetes of the young-12 (MODY12; 621196) who had severe microvascular diabetic complications, Timmers et al. (2021) identified heterozygosity for a c.3544C-T transition (c.3544C-T, NM_000352.6) in the ABCC8 gene that resulted in an arg1182-to-trp (R1182W) substitution. The mutation was present in 1/152,080 alleles in the gnomAD (v3.1) database. The mutation was subsequently identified in her mother, older daughter, and son. Her mother had diabetes which required only oral agents, and neither of her children had had neonatal diabetes. Timmers et al. (2021) noted that 2 transcripts for the ABCC8 gene differing in length by 1 amino acid arise by alternative splicing at exon 17; thus, residue R1182 may be referred to as R1183 according to another reference sequence. Timmers et al. (2021) identified 10 reports in the literature that included individuals with the R1182W mutation, with phenotypes of transient neonatal diabetes mellitus (TNDM2; 610374), permanent neonatal diabetes permanent neonatal diabetes mellitus (PNDM3; 618857), and MODY.

This is a variant with a reported allele frequency of 0.000003978 according to GnomAD. This, together with Clinvar reports on pathogenicity and variant effect predictor strengthens the indirect evidence for causality. The present mutation has mostly been associated with neonatal diabetes (Flanagan 2007, Batra 2009, Kong 2010, Bonnefond 2013, Beltrand 2015, Zhang 2015, Hashimoto 2016) and in only 3 papers reporting a MODY12 (Reilly 2019, Novak 2020, Gurtunca 2020).

Comment on clinical features:
Problem: A 35-year old woman presented in 2019 with: - a Charcot destruction of the left foot. - HbA1c of 14.2% or 132 mmol/mol with a low c-peptide (0.27 nmol/L at a glycemia of 228 mg/dl) without keto-acidosis. Medical record: - gestational diabetes in 2004, 2007 and 2012, for which she needed to be treated with insulin. - Between and after all three pregnancies, all therapy was stopped. - In 2006, at the fourth month of her second pregnancy: an HbA1c level of 8.1% or 65 mmol/mol with negative screening for Islet Cell Antibodies (ICA), insulin, Glutamic Acid Decarboxylase (GAD)-65 and Tyrosine Phosphatase (IA)-2 antibodies. Familial history: - a mother with type 2 diabetes mellitus, diagnosed a couple of years before, always an HbA1c of less than 7.0% or 53 mmol/mol on metformin monotherapy. No diabetic complications. - a maternal grandmother who had type 1 diabetes mellitus since juvenile age but deceased when the patient was twelve years old - the two siblings of the index patient (one brother and one sister respectively 33 and 31 years old) have no history of diabetes mellitus. - 3 children without diabetes mellitus or neonatal hypoglycemia Current work-up (during admission in 2019): - presence of severe non-proliferative diabetic retinopathy - discrete severe non-proliferative diabetic retinopathy - active sensori-motoric axonal demyelinating polyneuropathy on electromyography (EMG). - Cardiac ultrasound and evaluation of lower limb vasculature revealed no abnormalities. - minor dyslipidemia: total cholesterol 165 mg/dl; HDL cholesterol 36 mg/dl; LDL cholesterol 103 mg/dl and triglycerides of 108 mg/dl - body mass index (BMI) of 19.7 kg/m2 - no hypertension. Therapy: - insulin therapy was started with adequate glucose control. - intensive local wound care (including surgical debridements and negative pressure wound therapy), antibiotic therapy and offloading. -the arthropathy progressed rapidly necessitating a below-the-knee amputation. Genetic screening: A MODY screening unveiled a heterozygote c.3544C>T p.(Arg1182Trp) variant of the ATP-binding cassette transporter subfamily C member 8 (ABCC8) gene (reference sequence NM_000352.6), confirming the presence of a MODY12 in this patient. Subsequently, all available family members (her mother, oldest daughter and son) were screened and a heterozygote c.3544C>T p.(Arg1182Trp) variant was found in all of them

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
