Description

For these reasons, this variant has been classified as Pathogenic. 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: 522258). This premature translational stop signal has been observed in individual(s) with spinal muscular atrophy with respiratory distress (PMID: 17431882). This variant is present in population databases (rs557416644, gnomAD 0.0009%). This sequence change creates a premature translational stop signal (p.Gln302*) in the IGHMBP2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in IGHMBP2 are known to be pathogenic (PMID: 14681881, 25439726, 25568292).
