Genetic Variant NM_001393918.1:c.218G>C (chr19-1235806-C-G) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3

The NM_001393918.1(CBARP):c.218G>C(p.Cys73Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0000137 in 1,609,206 control chromosomes in the GnomAD database, including 1 homozygotes. 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. C73Y) has been classified as Uncertain significance.

Genes affected

CBARP (HGNC:28617): (CACN subunit beta associated regulatory protein) Predicted to enable transmembrane transporter binding activity. Predicted to be involved in negative regulation of calcium ion-dependent exocytosis and negative regulation of voltage-gated calcium channel activity. Predicted to be located in synaptic vesicle membrane. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. Predicted to colocalize with growth cone and secretory granule. [provided by Alliance of Genome Resources, Apr 2022]
