Genes affected
PPP1R42 (HGNC:33732): (protein phosphatase 1 regulatory subunit 42) The protein encoded by this gene can interact with gamma-tubulin and PP1 phosphatase, a regulator of centrosome separation. The encoded protein is a positive regulator of PP1 phosphatase and thus plays a role in the control of centrosome integrity. [provided by RefSeq, Feb 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2022The c.212C>A (p.A71D) alteration is located in exon 3 (coding exon 2) of the PPP1R42 gene. This alteration results from a C to A substitution at nucleotide position 212, causing the alanine (A) at amino acid position 71 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
