• NM_015226.3:c.613C>G

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2 BP4

The NM_015226.3(CLEC16A):​c.613C>G​(p.Gln205Glu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q205P) has been classified as Uncertain significance.

Genes affected

CLEC16A (HGNC:29013): (C-type lectin domain containing 16A) This gene encodes a member of the C-type lectin domain containing family. Single nucleotide polymorphisms in introns of this gene have been associated with diabetes mellitus, multiple sclerosis and rheumatoid arthritis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

CLEC16A Gene-Disease associations (from GenCC):

• schizophrenia

  Inheritance: Unknown Classification: NO_KNOWN Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.4002046).

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.613C>G (p.Q205E) alteration is located in exon 7 (coding exon 7) of the CLEC16A gene. This alteration results from a C to G substitution at nucleotide position 613, causing the glutamine (Q) at amino acid position 205 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
