Variant summary

Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1 PM2 PP3_Strong

The NM_004854.5(CHST10):​c.568G>T​(p.Asp190Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D190H) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: CHST10 NM_004854.5 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.71

Genes affected

CHST10 (HGNC:19650): (carbohydrate sulfotransferase 10) This protein encoded by this gene transfers sulfate to the C-3 hydroxyl of terminal glucuronic acid of protein- and lipid-linked oligosaccharides. This protein was first identified as a sulfotransferase that acts on the human natural killer-1 (HNK-1) glycan; HNK-1 is a carbohydrate involved in neurodevelopment and synaptic plasticity.[provided by RefSeq, Feb 2011]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM1: In a mutagenesis_site Induces a mild reduction in enzyme activity. (size 0) in uniprot entity CHSTA_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.953
