NM_001018116.2:c.702_722delAAGGCAGTCAGGAGAGAGGCT

Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 3P and 12B. PM4PP3BP6_Very_StrongBS2

The NM_001018116.2(CAVIN4):​c.702_722delAAGGCAGTCAGGAGAGAGGCT​(p.Arg235_Leu241del) variant causes a disruptive inframe deletion change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00332 in 1,614,020 control chromosomes in the GnomAD database, including 11 homozygotes. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Likely benign (★★).

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]

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. -
