Genes affected

PARD3 (HGNC:16051): (par-3 family cell polarity regulator) This gene encodes a member of the PARD protein family. PARD family members interact with other PARD family members and other proteins; they affect asymmetrical cell division and direct polarized cell growth. Multiple alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Oct 2011]

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=0.28728402).

The c.3620G>A (p.R1207Q) alteration is located in exon 24 (coding exon 24) of the PARD3 gene. This alteration results from a G to A substitution at nucleotide position 3620, causing the arginine (R) at amino acid position 1207 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
