One child had additional unique features of periventricular calcification, abnormal pterins and dry thickened skin.<h4>Methods</h4>Exome enrichment was performed on pooled genomic libraries from the two affected children and sequenced on an Illumina HiSeq2000. After quality control and variant identification, rare homozygous variants were prioritised. Respiratory chain complex activities were measured and normalised to citrate synthase activity in cultured patient fibroblasts. RMND1 protein levels were analysed by standard Western blotting.<h4>Results</h4>Exome sequencing iJIMD reportsPeriventricular Calcification, Abnormal Pterins and Dry Thickened Skin: Expanding the Clinical Spectrum of RMND1?PMC5580737G0601943Ennis SCasey JPPhilip RKTaylor RWThompson KTwomey EHe LLynch SACrushell EKing MDfalsePeriventricular Calcification, Abnormal Pterins and Dry Thickened Skin: Expanding the Clinical Spectrum of RMND1?<h4>Background</h4>We report a consanguineous Sudanese family whose two affected sons presented with a lethal disorder characterised by severe neonatal lactic acidosis, hypertonia, microcephaly and intractable seizures.
