We have studied the molecular bases of maple syrup urine disease by analyzing the activity, subunit structure, mRNA sequence, and the genome of the affected enzyme. The branched chain alpha-keto acid dehydrogenase (BCKDH) activity in the patient was 4.2-4.5% of the control level. Immunoblot analysis revealed that the E2 subunit of BCKDH (Mr 52,000) was absent and another protein band with an Mr of 49,000 was present. We amplified the cDNA of the E2 subunit obtained from the patient's cell using the polymerase chain reaction method, then sequenced the amplified cDNA, in which a 78-bp deletion was identified. The consanguineous parents and a sister had two species of mRNA; the one corresponding to the normal E2 subunit and the other with a 78-bp deletion, whereas findings in a brother were normal. The molecular size of the translation products as deduced from the abnormal mRNA sequence was compatible with an abnormal protein band (Mr 49,000) detected in the patient's cells by immunoblot analysis. Analysis of genomic DNA of BCKDH-E2 subunit revealed that the 78-bp deletion in the mRNA was caused by an exon skipping due to a single base deletion in the 5'-splice donor site. As a result of the mutation, part of the inner E2 core domain was omitted. The specified region of the inner E2 core domain was highly homologous to the region of the E2 subunit of pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase. These observations imply the biological importance of the region in the inner E2 core domain of BCKDH to maintain normal function of the activity.

Furthermore, we prioritized ten deep-intronic variants and three noncanonical splice site (NCSS) variants in 14 individuals using criteria in Alamut and SpliceAI (Supplementary Tables 3 and 4) outlined in the variant frequency and pathogenicity prediction parameters section of the methods. For the indel variants detected in ABCA4 (NG_009073.1, in Pt-28, Pt-29, and Pt-30), CYP4V2 (NG_007965.1, in Pt-52), and RLBP1 (NG_008116.1, in Pt-65), no SpliceAI scores were provided due to the nature of these variants. Therefore, inclusion of these three variants for in vitro splice assays was based on Alamut prediction scores only. The pathogenicity of noncoding variants was determined in seven cases (46.6%) after in vitro splice assays (see below) (Table 2 and Fig. 1). While employing WGS, significant progress was made in defining the genetic pathogenesis of IRDs in this prescreened IRD cohort; 76% of cases remained genetically unexplained.

In Pt-7, we identified a homozygous synonymous variant in the last nucleotide of CDHR1 exon 8, c.783G>A (NG_028034.1). In 2017, Stingl et al. reported that a patient was homozygous for the same variant. A midigene splice assay encompassing exons 7, 8, and 9 demonstrated that this variant causes in-frame skipping of exon 8 (p.Asp214_Pro261del)26. Likewise, a similar defect was identified in messenger RNA (mRNA) from the retina of an individual heterozygous for this variant. The authors suggest that this variant is associated with a relatively mild form of IRD, based on clinical examination of a patient homozygous for this variant26. Similarly, our patient displays a mild phenotype and late age-at-onset as previously described26.

In Pt-17, a pathogenic missense variant (c.1843G>A) was identified in HGSNAT (NG_009552.1) as the first allele. Through WGS analysis, a NCSS variant, c.493+5G>A, was identified in the same gene, resulting in exon 4 skipping (p.Arg124Serfs*25) as evaluated using a midigene splice assay spanning exons 3, 4, and 5 (Fig. 2a). The variant was classified as severe due to the absence of remaining wild-type mRNA when testing the mutant construct.

In addition, WGS facilitated the discovery of pathogenic noncoding variants that were not previously captured by TCS and WES. Two NCSS variants, i.e. HGSNAT, c.493+5G>A and USH2A, c.4758+3A>G, were detected using WGS. These noncoding variants were overlooked in earlier testing methods due to the lack of evidence for pathogenicity at the time of sequencing. After in vitro splice assays of these variants, they were both classified as severe due to the presence of

In Pt-7, we identified CDHR1 c.783G>A in a homozygous state, which previously was determined to lead to in-frame skipping of exon 8 (p.Asp214_Pro261del)26. No other potentially causative variants were identified as part of our analysis. The allele frequency of this variant (total allele frequency of 0.003052 and allele frequency of 0.004903 in non-Finnish Europeans; Supplementary Table 6) indicates that this variant may not be fully penetrant or acts as a hypomorphic allele. The splice defect is in-frame and may confer a subtle change in protein function. Additionally, Stingl et al. showed reduced expression of the mutant allele by comparison with the wild type26. In line with this, Pt-7 displays a mild phenotype consistent with previously described CDHR1-related disease and late age at disease onset26. It is also possible that other genetic factors affect the penetrance of this variant, potentially explaining the relatively high allele frequency35.

The manual variant prioritization approach differed depending on the findings of previous genetic studies. In cases where no first candidate variant was identified during previous genetic testing efforts, CNVs and SVs were evaluated first followed by assessment of SNVs. Subsequently, SNVs were manually prioritized according to their predicted pathogenic effect (i.e., nonsense, frameshift, canonical splice site variants, NCSS variants, in-frame deletions/insertions, missense variants, and synonymous variants). Coding or noncoding SNVs with a minor allele frequency of >1% in the gnomAD database were not considered causative22. Once a candidate pathogenic variant was identified, the predicted effects of rare intronic variants (with allele frequency

For FTTH installation and deployment, mechanical connectors have been widely used, however unstable quality , weak durability and high maintenance cost might be of a concern, splice-on connectors are invented to provide a more solid solution for FTTH installation. Splice on connector technology has made it an integration with fusion splicing machine to improve the field work efficiency dramatically. The splice-on connector can be used not only in the filed of communication but also widely used in advanced technical fields including military, ship-building, medical, power plant and most of FTTH network solution.

Significantly reduce material waste and maintain production speed while splicing new material rolls. Our Low Roll Splice Initiation System automatically initiates the splice at-speed when minimum material is remaining on the roll core. Optical technology analyzes every roll core individually since each one is unique, eliminating errors caused by core diameter variations between different raw materials for accurate and consistent splice set-up each time.

The manual splice tool has an ergonomic rubber handle for a soft comfortable grip and can be used with single brass shims. A semi-automatic splice tool eliminates handling of individual shims by pre-loading a bandolier of brass shims into the tool to speed the splicing process. Lock clamps are located at either end of the platen which assist in holding the carrier tape in place and make it easier to splice.

Single and bandolier brass shims provide a secure, precise and reliable connection when joining two tapes. Single shims suit the SMT manual splice tool when joining carrier tape. Bandolier shims are used with the semi-automatic splice tool which holds 20 brass shims. e24fc04721
