Genetic Variant PCDH12:p.Ser1178_Ser1179insGlyGlySerSerSerSerSer (chr5-141945401-T-TGCTGCTGCTGCTGCTGCCGCC) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_016580.4(PCDH12):c.3534_3535insGGCGGCAGCAGCAGCAGCAGC(p.Ser1178_Ser1179insGlyGlySerSerSerSerSer) variant causes a conservative inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,202 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

PCDH12 (HGNC:8657): (protocadherin 12) This gene belongs to the protocadherin gene family, a subfamily of the cadherin superfamily. The encoded protein consists of an extracellular domain containing 6 cadherin repeats, a transmembrane domain and a cytoplasmic tail that differs from those of the classical cadherins. The gene localizes to the region on chromosome 5 where the protocadherin gene clusters reside. The exon organization of this transcript is similar to that of the gene cluster transcripts, notably the first large exon, but no significant sequence homology exists. The function of this cellular adhesion protein is undetermined but mouse protocadherin 12 does not bind catenins and appears to have no affect on cell migration or growth.

DELE1 (HGNC:28969): (DAP3 binding cell death enhancer 1) Enables protein kinase binding activity and protein serine/threonine kinase activator activity. Involved in HRI-mediated signaling; extrinsic apoptotic signaling pathway via death domain receptors; and regulation of cysteine-type endopeptidase activity involved in apoptotic process. Located in cytosol and mitochondrial inner membrane. [provided by Alliance of Genome Resources, Apr 2022]
