Genes affected

NFATC2IP (HGNC:25906): (nuclear factor of activated T cells 2 interacting protein) Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

NFATC2IP-AS1 (HGNC:56085): (NFATC2IP antisense RNA 1)

MIR4517 (HGNC:41878): (microRNA 4517) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.26416555).

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.909G>C (p.R303S) alteration is located in exon 6 (coding exon 6) of the NFATC2IP gene. This alteration results from a G to C substitution at nucleotide position 909, causing the arginine (R) at amino acid position 303 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
