Genes affected

RBM28 (HGNC:21863): (RNA binding motif protein 28) The protein encoded by this gene is a specific nucleolar component of the spliceosomal small nuclear ribonucleoprotein (snRNP)complexes . It specifically associates with U1, U2, U4, U5, and U6 small nuclear RNAs (snRNAs), possibly coordinating their transition through the nucleolus. Mutation in this gene causes alopecia, progressive neurological defects, and endocrinopathy (ANE syndrome), a pleiotropic and clinically heterogeneous disorder. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

Sep 26, 2022

The c.1903C>T (p.P635S) alteration is located in exon 17 (coding exon 17) of the RBM28 gene. This alteration results from a C to T substitution at nucleotide position 1903, causing the proline (P) at amino acid position 635 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
