Genes affected

SRSF9 (HGNC:10791): (serine and arginine rich splicing factor 9) The protein encoded by this gene is a member of the serine/arginine (SR)-rich family of pre-mRNA splicing factors, which constitute part of the spliceosome. Each of these factors contains an RNA recognition motif (RRM) for binding RNA and an RS domain for binding other proteins. The RS domain is rich in serine and arginine residues and facilitates interaction between different SR splicing factors. In addition to being critical for mRNA splicing, the SR proteins have also been shown to be involved in mRNA export from the nucleus and in translation. Two pseudogenes, one on chromosome 15 and the other on chromosome 21, have been found for this gene. [provided by RefSeq, Sep 2010]

GATC (HGNC:25068): (glutamyl-tRNA amidotransferase subunit C) Enables glutaminyl-tRNA synthase (glutamine-hydrolyzing) activity. Involved in glutaminyl-tRNAGln biosynthesis via transamidation and mitochondrial translation. Located in mitochondrion. Part of glutamyl-tRNA(Gln) amidotransferase complex. Implicated in combined oxidative phosphorylation deficiency 42. [provided by Alliance of Genome Resources, Apr 2022]

The c.644T>A (p.F215Y) alteration is located in exon 4 (coding exon 4) of the SRSF9 gene. This alteration results from a T to A substitution at nucleotide position 644, causing the phenylalanine (F) at amino acid position 215 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
