Genes affected
ELMO2 (HGNC:17233): (engulfment and cell motility 2) The protein encoded by this gene interacts with the dedicator of cyto-kinesis 1 protein. Similarity to a C. elegans protein suggests that this protein may function in phagocytosis of apoptotic cells and in cell migration. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.062413316 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5.6, offset of 26, new splice context is: gtgGTaggc. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 20-46375235-C-T is Pathogenic according to our data. Variant chr20-46375235-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 254191.Status of the report is no_assertion_criteria_provided, 0 stars.
