Genes affected
RXYLT1 (HGNC:13530): (ribitol xylosyltransferase 1) This gene encodes a type II transmembrane protein that is thought to have glycosyltransferase function. Mutations in this gene result in cobblestone lissencephaly. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.66).
BP6
Variant 12-63780002-C-T is Benign according to our data. Variant chr12-63780002-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 723799.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=-0.719 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.000109 (159/1459114) while in subpopulation SAS AF= 0.00175 (151/86230). AF 95% confidence interval is 0.00152. There are 5 homozygotes in gnomad4_exome. There are 119 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 5 AR gene
