Genes affected

RPL5 (HGNC:10360): (ribosomal protein L5) 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 L18P family of ribosomal proteins and component of the 60S subunit. The encoded protein binds 5S rRNA to form a stable complex called the 5S ribonucleoprotein particle (RNP), which is necessary for the transport of nonribosome-associated cytoplasmic 5S rRNA to the nucleolus for assembly into ribosomes. The encoded protein may also function to inhibit tumorigenesis through the activation of downstream tumor suppressors and the downregulation of oncoprotein expression. Mutations in this gene have been identified in patients with Diamond-Blackfan Anemia (DBA). This gene is co-transcribed with the small nucleolar RNA gene U21, which is located in its fifth intron. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed throughout the genome. [provided by RefSeq, Mar 2017]

DIPK1A (HGNC:32213): (divergent protein kinase domain 1A) This gene encodes a member of the FAM69 family of cysteine-rich type II transmembrane proteins. These proteins localize to the endoplasmic reticulum but their specific functions are unknown. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

SNORD21 (HGNC:10144): (small nucleolar RNA, C/D box 21) This gene encodes a small nucleolar RNA (snoRNA) that may be involved in biogenesis of the large (28S) ribosomal subunit. This gene is found within an intron of the RPL5 gene. [provided by RefSeq, Mar 2009]

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-92837592-C-T is Pathogenic according to our data. Variant chr1-92837592-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 100639.Status of the report is criteria_provided_single_submitter, 1 stars.
