Genes affected
MRPL3 (HGNC:10379): (mitochondrial ribosomal protein L3) Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 39S subunit protein that belongs to the L3P ribosomal protein family. A pseudogene corresponding to this gene is found on chromosome 13q. [provided by RefSeq, Jul 2008]

ACMG classification
Classification made for transcript
Verdict is Benign. Variant got -12 ACMG points.
BP4
?
Computational evidence support a benign effect (BayesDel_noAF=-0.8).
BS1
?
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0125 (1905/152338) while in subpopulation EAS AF= 0.0351 (182/5180). AF 95% confidence interval is 0.031. There are 17 homozygotes in gnomad4. There are 946 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
