Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The ENST00000307839.10(RPL15):​c.87G>T​(p.Gln29His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q29K) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: RPL15 ENST00000307839.10 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 1.63

Genes affected

RPL15 (HGNC:10306): (ribosomal protein L15) Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of four RNA species and approximately 80 structurally distinct proteins. This gene encodes a member of the L15E family of ribosomal proteins and a component of the 60S subunit. This gene shares sequence similarity with the yeast ribosomal protein YL10 gene. Elevated expression of this gene has been observed in esophageal tumors and gastric cancer tissues, and deletion of this gene has been observed in a Diamond-Blackfan anemia (DBA) patient. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Mar 2017]

RPL15 (HGNC:):

NKIRAS1 (HGNC:17899): (NFKB inhibitor interacting Ras like 1) Predicted to enable GTPase activating protein binding activity. Predicted to be involved in I-kappaB kinase/NF-kappaB signaling. Predicted to act upstream of or within several processes, including Ral protein signal transduction; lung alveolus development; and surfactant homeostasis. Located in cytosol and endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]
