Genes affected
CMC1 (HGNC:28783): (C-X9-C motif containing 1) Predicted to enable metal ion binding activity. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
AZI2 (HGNC:24002): (5-azacytidine induced 2) AZI2, or NAP1, contributes to the activation of NFKB (see MIM 164011)-dependent gene expression by activating IKK-related kinases, such as NAK (TBK1; MIM 604834) (Fujita et al., 2003 [PubMed 14560022]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.125G>A (p.C42Y) alteration is located in exon 3 (coding exon 3) of the CMC1 gene. This alteration results from a G to A substitution at nucleotide position 125, causing the cysteine (C) at amino acid position 42 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
