Genes affected

SEBOX (HGNC:32942): (SEBOX homeobox) Homeodomain proteins, such as SEBOX, play a key role in coordinating gene expression during development (Cinquanta et al., 2000 [PubMed 10922053]).[supplied by OMIM, Mar 2008]

ENSG00000273171 (HGNC:):

SARM1 (HGNC:17074): (sterile alpha and TIR motif containing 1) Enables NAD+ nucleotidase, cyclic ADP-ribose generating and identical protein binding activity. Involved in NAD catabolic process; positive regulation of neuron death; and response to axon injury. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2809055).

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.212A>G (p.N71S) alteration is located in exon 2 (coding exon 2) of the SEBOX gene. This alteration results from a A to G substitution at nucleotide position 212, causing the asparagine (N) at amino acid position 71 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
