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.

LBHD1 links:

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.

The c.334G>T (p.D112Y) alteration is located in exon 4 (coding exon 3) of the LBHD1 gene. This alteration results from a G to T substitution at nucleotide position 334, causing the aspartic acid (D) at amino acid position 112 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
