Genes affected

ARID3C (HGNC:21209): (AT-rich interaction domain 3C) This gene is a member of the ARID (AT-rich interaction domain) family of proteins. The ARID domain is a helix-turn-helix motif-based DNA-binding domain. ARID family members have roles in embryonic patterning, cell lineage gene regulation, cell cycle control, transcriptional regulation and possibly in chromatin structure modification.

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.963

Collection Method: clinical testing

The c.526C>T (p.L176F) alteration is located in exon 3 (coding exon 3) of the ARID3C gene. This alteration results from a C to T substitution at nucleotide position 526, causing the leucine (L) at amino acid position 176 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
