Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 2P and 10B. PM4BP6_ModerateBS1BS2

The NM_012090.5(MACF1):c.56_57insATGTCGGAGTGAGCGGTCATGTCGGAGTGAGCGGTC(p.Ser19_Cys20insCysArgSerGluArgSerCysArgSerGluArgSer) variant causes a disruptive inframe insertion change. The variant allele was found at a frequency of 0.0000788 in 152,292 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Benign (★).

Genes affected

MACF1 (HGNC:13664): (microtubule actin crosslinking factor 1) This gene encodes a large protein containing numerous spectrin and leucine-rich repeat (LRR) domains. The encoded protein is a member of a family of proteins that form bridges between different cytoskeletal elements. This protein facilitates actin-microtubule interactions at the cell periphery and couples the microtubule network to cellular junctions. Alternative splicing results in multiple transcript variants, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, May 2013]
