NM_030652.4:c.724G>A

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_030652.4(EGFL8):​c.724G>A​(p.Val242Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000622 in 1,608,750 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V242L) has been classified as Uncertain significance.

Genes affected
EGFL8 (HGNC:13944): (EGF like domain multiple 8) Predicted to enable signaling receptor binding activity. Predicted to be involved in anatomical structure development. Predicted to act upstream of or within in utero embryonic development. Predicted to be active in cell surface and extracellular region. [provided by Alliance of Genome Resources, Apr 2022]
PPT2-EGFL8 (HGNC:48343): (PPT2-EGFL8 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring PPT2 (palmitoyl-protein thioesterase 2) and EGFL8 (EGF-like-domain, multiple 8) genes located in the major histocompatibility complex class III region of chromosome 6. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]
