Description

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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 434550). This variant has been observed in individuals with clinical features of autosomal recessive neurodegeneration with brain iron accumulation (PMID: 23269600, 29915382). This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change falls in intron 2 of the C19orf12 gene. It does not directly change the encoded amino acid sequence of the C19orf12 protein. It affects a nucleotide within the consensus splice site.
