Genes affected

ELMO1 (HGNC:16286): (engulfment and cell motility 1) This gene encodes a member of the engulfment and cell motility protein family. These proteins interact with dedicator of cytokinesis proteins to promote phagocytosis and cell migration. Increased expression of this gene and dedicator of cytokinesis 1 may promote glioma cell invasion, and single nucleotide polymorphisms in this gene may be associated with diabetic nephropathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

ELMO1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ELMO1. . Gene score misZ 3.1294 (greater than the threshold 3.09). Trascript score misZ 4.0843 (greater than threshold 3.09). GenCC has associacion of gene with male infertility with azoospermia or oligozoospermia due to single gene mutation.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.936

The c.1199T>C (p.L400P) alteration is located in exon 15 (coding exon 14) of the ELMO1 gene. This alteration results from a T to C substitution at nucleotide position 1199, causing the leucine (L) at amino acid position 400 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
