| Allelic Variant 1 |
613468.0002; FARBER LIPOGRANULOMATOSIS |
| Identified Mutation |
GLU138VAL; In a patient with Farber lipogranulomatosis Li et al. (1999) demonstrated a glu138-to-val (E138V) mutation in the ASAH gene as a result of a 413A-T transversion. |

GLU138VAL; In a patient with Farber lipogranulomatosis Li et al. (1999) demonstrated a glu138-to-val (E138V) mutation in the ASAH gene as a result of a 413A-T transversion. |
| Remarks |
Clinically affected; mild disease (Farber disease subtype 3); late onset of disease at 20 months; died at age 30; a sister with similar clinical history died at age 18; deficient acid ceramidase; donor subject is homozygous for an A>T transversion at nucleotide 413 in exon 6 of the ASAH gene resulting in the substitution of valine for glutamic acid at codon 138 [Glu138Val (E138V)] |
