Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2

The NM_015330.6(SPECC1L):c.464G>T(p.Arg155Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000547 in 1,461,888 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R155C) has been classified as Benign.

Genes affected

SPECC1L (HGNC:29022): (sperm antigen with calponin homology and coiled-coil domains 1 like) This gene encodes a coiled-coil domain containing protein. The encoded protein may play a critical role in actin-cytoskeletal reorganization during facial morphogenesis. Mutations in this gene are a cause of oblique facial clefting-1. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. A read-through transcript composed of SPECC1L (sperm antigen with calponin homology and coiled-coil domains 1-like) and the downstream ADORA2A (adenosine A2a receptor) gene sequence has been identified, but it is thought to be non-coding.

SPECC1L links:

SPECC1L-ADORA2A (HGNC:49185): (SPECC1L-ADORA2A readthrough (NMD candidate)) This locus represents naturally occurring readthrough transcription between the neighboring SPECC1L (sperm antigen with calponin homology and coiled-coil domains 1-like) and ADORA2A (adenosine A2a receptor) genes on chromosome 22. The readthrough transcript is a candidate for nonsense-mediated mRNA decay (NMD) and is unlikely to produce a protein product. [provided by RefSeq, Jun 2013]
