Genes affected

CYB5RL (HGNC:32220): (cytochrome b5 reductase like) Predicted to enable cytochrome-b5 reductase activity, acting on NAD(P)H. Predicted to be involved in bicarbonate transport. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

MRPL37 (HGNC:14034): (mitochondrial ribosomal protein L37) 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. [provided by RefSeq, Jul 2008]

The c.32C>G (p.T11S) alteration is located in exon 3 (coding exon 1) of the CYB5RL gene. This alteration results from a C to G substitution at nucleotide position 32, causing the threonine (T) at amino acid position 11 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
