Genes affected

MRPL9 (HGNC:14277): (mitochondrial ribosomal protein L9) This is a nuclear gene encoding a protein component of the 39S subunit of the mitochondrial ribosome. Alternative splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 8. [provided by RefSeq, Jul 2014]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• BS2: High Homozygotes in GnomAdExome4 at 5 AR gene
