Genes affected

BMS1 (HGNC:23505): (BMS1 ribosome biogenesis factor) This gene likely encodes a ribosome assembly protein. A similar protein in yeast functions in 35S-rRNA processing, which includes a series of cleavage steps critical for formation of 40S ribosomes. Related pseudogenes exist on chromosomes 2, 9, 10, 15, 16, and 22.[provided by RefSeq, Mar 2009]

The c.155G>A (p.R52Q) alteration is located in exon 2 (coding exon 1) of the BMS1 gene. This alteration results from a G to A substitution at nucleotide position 155, causing the arginine (R) at amino acid position 52 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
