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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MACF1. . Gene score misZ 0.58309 (greater than the threshold 3.09). Trascript score misZ 6.2367 (greater than threshold 3.09). GenCC has associacion of gene with lissencephaly spectrum disorder with complex brainstem malformation, lissencephaly 9 with complex brainstem malformation.

BP4

Computational evidence support a benign effect (MetaRNN=0.25979847).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000145 (22/152152) while in subpopulation NFE AF= 0.000265 (18/68006). AF 95% confidence interval is 0.000171. There are 0 homozygotes in gnomad4. There are 10 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 22 AD gene.

Ambry Genetics

Oct 06, 2021

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
