Genes affected

HMBS (HGNC:4982): (hydroxymethylbilane synthase) This gene encodes a member of the hydroxymethylbilane synthase superfamily. The encoded protein is the third enzyme of the heme biosynthetic pathway and catalyzes the head to tail condensation of four porphobilinogen molecules into the linear hydroxymethylbilane. Mutations in this gene are associated with the autosomal dominant disease acute intermittent porphyria. Alternatively spliced transcript variants encoding different isoforms have been described.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000225 (15/66804) while in subpopulation SAS AF= 0.000765 (1/1308). AF 95% confidence interval is 0.000295. There are 0 homozygotes in gnomad4. There are 11 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.

BS2

High Homozygotes in GnomAdExome4 at 213 SD gene
