Genes affected

PPM1E (HGNC:19322): (protein phosphatase, Mg2+/Mn2+ dependent 1E) This gene encodes a member of the PPM family of serine/threonine-protein phosphatases. The encoded protein is localized to the nucleus and dephosphorylates and inactivates multiple substrates including serine/threonine-protein kinase PAK 1, 5'-AMP-activated protein kinase (AMPK) and the multifunctional calcium/calmodulin-dependent protein kinases. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, May 2012]

TRIM37 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07726255).

The c.1966C>G (p.Q656E) alteration is located in exon 7 (coding exon 7) of the PPM1E gene. This alteration results from a C to G substitution at nucleotide position 1966, causing the glutamine (Q) at amino acid position 656 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
