Variant names:

• chr10-74200777-T-G
• rs781661838
• NM_006721.4:c.79T>G

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_006721.4(ADK):​c.79T>G​(p.Phe27Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 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. F27L) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: ADK NM_006721.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.45
• Publications: 1 publications found

Genes affected

ADK (HGNC:257): (adenosine kinase) This gene an enzyme which catalyzes the transfer of the gamma-phosphate from ATP to adenosine, thereby serving as a regulator of concentrations of both extracellular adenosine and intracellular adenine nucleotides. Adenosine has widespread effects on the cardiovascular, nervous, respiratory, and immune systems and inhibitors of the enzyme could play an important pharmacological role in increasing intravascular adenosine concentrations and acting as anti-inflammatory agents. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2011]

ADK Gene-Disease associations (from GenCC):

• adenosine kinase deficiency

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE, LIMITED Submitted by: G2P, Orphanet, Labcorp Genetics (formerly Invitae), ClinGen

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
