Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego RCV000853363 SCV000996231 likely pathogenic Sulfite oxidase deficiency due to molybdenum cofactor deficiency type A 2018-12-31 criteria provided, single submitter clinical testing This variant has not been previously reported or functionally characterized in the literature to our knowledge, but a variant at the adjacent nucleotide (c.*7+6T>C) has been previously reported in a patient with molybdenum cofactor deficiency (PMID: 19544009). It is present in the heterozygous state in the gnomAD population database at a frequency of 0.002% (6/251428) and thus is presumed to be rare. Multiple splice prediction tools suggest this variant is likely interfere with normal splicing. Based on the available evidence, the c.*7+5G>A variant is classified as a variant of uncertain significance.
Labcorp Genetics (formerly Invitae), Labcorp RCV000853363 SCV002171308 uncertain significance Sulfite oxidase deficiency due to molybdenum cofactor deficiency type A 2024-10-12 criteria provided, single submitter clinical testing This sequence change falls in intron 10 of the MOCS1 gene. It does not directly change the encoded amino acid sequence of the MOCS1 protein. This variant is present in population databases (rs752653792, gnomAD 0.01%). This variant has been observed in individual(s) with molybdenum cofactor deficiency (PMID: 32014857). This variant is also known as c.*7+5G>A. ClinVar contains an entry for this variant (Variation ID: 692068). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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.
