dbSNP rs201229537: MRPS2:p.Asp114Asn (chr9-135503582-G-A) – ACMG Classification: Likely_pathogenic (6 pts)

Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 7P and 1B. PS3PM5PP5BP4

The NM_016034.5(MRPS2):c.340G>A(p.Asp114Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000062 in 1,613,612 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). ClinVar reports functional evidence for this variant: "SCV000883273: PS3 upgraded in strength to Very Strong (https://www.ncbi.nlm.nih.gov/pubmed/29576219).". Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D114E) has been classified as Likely pathogenic.

Genes affected

MRPS2 (HGNC:14495): (mitochondrial ribosomal protein S2) 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 28S subunit protein that belongs to the ribosomal protein S2 family. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, May 2012]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000883273: PS3 upgraded in strength to Very Strong (https://www.ncbi.nlm.nih.gov/pubmed/29576219).

PM5

Other missense variant is known to change same aminoacid residue: Variant chr9-135503584-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 3900679.

PP5

Variant 9-135503582-G-A is Pathogenic according to our data. Variant chr9-135503582-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 523224.

BP4

Computational evidence support a benign effect (MetaRNN=0.32183754). . Strength limited to SUPPORTING due to the PP5.
