Genes affected

RAPSN (HGNC:9863): (receptor associated protein of the synapse) This gene encodes a member of a family of proteins that are receptor associated proteins of the synapse. The encoded protein contains a conserved cAMP-dependent protein kinase phosphorylation site, and plays a critical role in clustering and anchoring nicotinic acetylcholine receptors at synaptic sites by linking the receptors to the underlying postsynaptic cytoskeleton, possibly by direct association with actin or spectrin. Mutations in this gene may play a role in postsynaptic congenital myasthenic syndromes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 0 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.37).

BP6

Variant 11-47441227-T-C is Benign according to our data. Variant chr11-47441227-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 259632.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00203 (309/152236) while in subpopulation AFR AF= 0.00684 (284/41538). AF 95% confidence interval is 0.00618. There are 0 homozygotes in gnomad4. There are 130 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
