Genes affected

LMF1 (HGNC:14154): (lipase maturation factor 1) Involved in triglyceride metabolic process. Predicted to be integral component of membrane. Predicted to be active in endoplasmic reticulum membrane. Implicated in familial lipase maturation factor 1 deficiency. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000342 (20/585324) while in subpopulation AMR AF= 0.00164 (18/11008). AF 95% confidence interval is 0.00106. There are 1 homozygotes in gnomad4_exome. There are 7 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck.
