Genes affected
RBM4B (HGNC:28842): (RNA binding motif protein 4B) Enables RNA binding activity. Predicted to be involved in entrainment of circadian clock by photoperiod; mRNA splicing, via spliceosome; and regulation of gene expression. Predicted to act upstream of or within positive regulation of gene expression. Located in cytosol and nucleoplasm. Part of protein-containing complex.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2022The c.977G>A (p.S326N) alteration is located in exon 3 (coding exon 2) of the RBM4B gene. This alteration results from a G to A substitution at nucleotide position 977, causing the serine (S) at amino acid position 326 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
