Genes affected

LBHD1 (HGNC:28351): (LBH domain containing 1) This gene shares three exons in common with another gene, chromosome 11 open reading frame 98 (GeneID:102288414), but the encoded protein uses a reading frame that is different from that of the chromosome 11 open reading frame 98 gene.

CSKMT (HGNC:33113): (citrate synthase lysine methyltransferase) Enables protein-lysine N-methyltransferase activity. Involved in peptidyl-lysine dimethylation; peptidyl-lysine monomethylation; and peptidyl-lysine trimethylation. Predicted to be located in mitochondrion.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.521C>T (p.P174L) alteration is located in exon 4 (coding exon 3) of the LBHD1 gene. This alteration results from a C to T substitution at nucleotide position 521, causing the proline (P) at amino acid position 174 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
