Genes affected
PARD6B (HGNC:16245): (par-6 family cell polarity regulator beta) This gene is a member of the PAR6 family and encodes a protein with a PSD95/Discs-large/ZO1 (PDZ) domain, an OPR domain and a semi-Cdc42/Rac interactive binding (CRIB) domain. This cytoplasmic protein is involved in asymmetrical cell division and cell polarization processes as a member of a multi-protein complex. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.164A>G (p.N55S) alteration is located in exon 2 (coding exon 2) of the PARD6B gene. This alteration results from a A to G substitution at nucleotide position 164, causing the asparagine (N) at amino acid position 55 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
