Genes affected

CCHCR1 (HGNC:13930): (coiled-coil alpha-helical rod protein 1) This gene encodes a protein with five coiled-coil alpha-helical rod domains that is thought to act as a regulator of mRNA metabolism through its interaction with mRNA-decapping protein 4. It localizes to P-bodies, the site of mRNA metabolism, with an N-terminus that is required for this subcellular localization, suggesting it is a P-body component. Naturally occurring mutations in this gene are associated with psoriasis. [provided by RefSeq, May 2017]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002022177).
• BP6: Variant 6-31154723-G-A is Benign according to our data. Variant chr6-31154723-G-A is described in ClinVar as [Benign]. Clinvar id is 1242555.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.212 is higher than 0.05.
