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 Gene-Disease associations (from GenCC):

• male infertility with azoospermia or oligozoospermia due to single gene mutation

  Inheritance: AR Classification: MODERATE Submitted by: King Faisal Specialist Hospital and Research Center

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.842

Collection Method: clinical testing

The c.983G>T (p.R328L) alteration is located in exon 13 (coding exon 12) of the ELMO1 gene. This alteration results from a G to T substitution at nucleotide position 983, causing the arginine (R) at amino acid position 328 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
