Variant summary

Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PS1 PM2 PP3 PP5

The ENST00000373477.9(YARS1):​c.241_242delinsAT​(p.Asp81Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin Lovd. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D81H) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)

Genes affected

YARS1 (HGNC:12840): (tyrosyl-tRNA synthetase 1) Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. Tyrosyl-tRNA synthetase belongs to the class I tRNA synthetase family. Cytokine activities have also been observed for the human tyrosyl-tRNA synthetase, after it is split into two parts, an N-terminal fragment that harbors the catalytic site and a C-terminal fragment found only in the mammalian enzyme. The N-terminal fragment is an interleukin-8-like cytokine, whereas the released C-terminal fragment is an EMAP II-like cytokine. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PS1: Transcript ENST00000373477.9 (YARS1) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in Lovd
• PM2: Very rare variant in population databases, with high coverage
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• PP5: Variant 1-32810729-TC-AT is Pathogenic according to our data. Variant chr1-32810729-TC-AT is described in ClinVar as [Pathogenic]. Clinvar id is 187863.Status of the report is no_assertion_criteria_provided, 0 stars.
