Genes affected

FTSJ1 (HGNC:13254): (FtsJ RNA 2'-O-methyltransferase 1) This gene encodes a member of the methyltransferase superfamily. The encoded protein localizes to the nucleolus, binds to S-adenosylmethionine, and may be involved in the processing and modification of ribosomal RNA. Mutations in this gene are associated with cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

The c.193G>A (p.G65S) alteration is located in exon 4 (coding exon 3) of the FTSJ1 gene. This alteration results from a G to A substitution at nucleotide position 193, causing the glycine (G) at amino acid position 65 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
