Genes affected
CARHSP1 (HGNC:17150): (calcium regulated heat stable protein 1) Enables mRNA 3'-UTR binding activity. Predicted to be involved in regulation of mRNA stability. Predicted to be located in P granule and cytosol. Predicted to be active in cytoplasm. Predicted to colocalize with cytoplasmic exosome (RNase complex). [provided by Alliance of Genome Resources, Apr 2022]
PMM2 (HGNC:9115): (phosphomannomutase 2) The protein encoded by this gene catalyzes the isomerization of mannose 6-phosphate to mannose 1-phosphate, which is a precursor to GDP-mannose necessary for the synthesis of dolichol-P-oligosaccharides. Mutations in this gene have been shown to cause defects in glycoprotein biosynthesis, which manifests as carbohydrate-deficient glycoprotein syndrome type I. [provided by RefSeq, Jul 2008]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 29, 2023 | The c.68C>G (p.T23S) alteration is located in exon 2 (coding exon 1) of the CARHSP1 gene. This alteration results from a C to G substitution at nucleotide position 68, causing the threonine (T) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
