Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS2

The NM_006387.6(CHERP):​c.2320C>T​(p.Arg774Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000136 in 1,613,790 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R774H) has been classified as Uncertain significance.

Genes affected
CHERP (HGNC:16930): (calcium homeostasis endoplasmic reticulum protein) Enables transmembrane transporter binding activity. Involved in positive regulation of calcineurin-NFAT signaling cascade and release of sequestered calcium ion into cytosol. Acts upstream of or within cellular calcium ion homeostasis and negative regulation of cell population proliferation. Located in perinuclear region of cytoplasm.

C19orf44 (HGNC:26141): (chromosome 19 open reading frame 44)
C19orf44 Gene-Disease associations (from GenCC):
  • inherited retinal dystrophy
