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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2022The c.841G>A (p.E281K) alteration is located in exon 3 (coding exon 3) of the PARD6B gene. This alteration results from a G to A substitution at nucleotide position 841, causing the glutamic acid (E) at amino acid position 281 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
