Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_032437.4(EFCAB7):ā€‹c.53C>Gā€‹(p.Pro18Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000138 in 1,444,274 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. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P18S) has been classified as Uncertain significance.

Genes affected
EFCAB7 (HGNC:29379): (EF-hand calcium binding domain 7) Predicted to enable calcium ion binding activity. Predicted to be involved in positive regulation of protein import into nucleus; positive regulation of protein localization to ciliary membrane; and positive regulation of transcription by RNA polymerase II. Predicted to be located in ciliary membrane. Predicted to be extrinsic component of membrane. Predicted to be part of plasma membrane protein complex. [provided by Alliance of Genome Resources, Apr 2022]
ITGB3BP (HGNC:6157): (integrin subunit beta 3 binding protein) This gene encodes a transcriptional coregulator that binds to and enhances the activity of members of the nuclear receptor families, thyroid hormone receptors and retinoid X receptors. This protein also acts as a corepressor of NF-kappaB-dependent signaling. This protein induces apoptosis in breast cancer cells through a caspase 2-mediated signaling pathway. This protein is also a component of the centromere-specific histone H3 variant nucleosome associated complex (CENP-NAC) and may be involved in mitotic progression by recruiting the histone H3 variant CENP-A to the centromere. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024The c.53C>G (p.P18R) alteration is located in exon 2 (coding exon 1) of the EFCAB7 gene. This alteration results from a C to G substitution at nucleotide position 53, causing the proline (P) at amino acid position 18 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
