Genes affected

CAVIN4 (HGNC:33742): (caveolae associated protein 4) This gene encodes a protein containing two coiled-coil regions. The encoded protein promotes Rho/ROCK (Rho-kinase) signaling in cardiac muscles cells, and may facilitate myofibrillar organization. [provided by RefSeq, Jun 2013]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• PM4: Nonframeshift variant in NON repetitive region in NM_001018116.2.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• BP6: Variant 9-100586047-AGAGAGAGGCTAAGGCAGTCAG-A is Benign according to our data. Variant chr9-100586047-AGAGAGAGGCTAAGGCAGTCAG-A is described in ClinVar as [Likely_benign]. Clinvar id is 227559.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS2: High Homozygotes in GnomAdExome4 at 10 AR gene

p.Leu248_Arg254del in exon 2 of MURC: This variant falls within a 7 amino acid r epeat (LRQSGER) and results in the removal of one repeat unit as compared to the reference sequence. Although it has been reported in three individuals with car diomyopathy (Rodriguez 2011), it is not expected to have clinical significance b ecause it has also been identified in 0.6% (369/66702) of European chromosomes b y the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Moreo ver, this region lacks conservation across species, and >5 mammals show a loss o f a single repeat unit within this region. -
