Our verdict is Benign. Variant got -10 ACMG points: 0P and 10B. BP6_ModerateBS1BS2
The NM_001079802.2(FKTN):c.-191delT variant causes a 5 prime UTR change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00904 in 152,256 control chromosomes in the GnomAD database, including 21 homozygotes. Variant has been reported in ClinVar as Benign (★).
FKTN (HGNC:3622): (fukutin) The protein encoded by this gene is a putative transmembrane protein that is localized to the cis-Golgi compartment, where it may be involved in the glycosylation of alpha-dystroglycan in skeletal muscle. The encoded protein is thought to be a glycosyltransferase and could play a role in brain development. Defects in this gene are a cause of Fukuyama-type congenital muscular dystrophy (FCMD), Walker-Warburg syndrome (WWS), limb-girdle muscular dystrophy type 2M (LGMD2M), and dilated cardiomyopathy type 1X (CMD1X). Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Nov 2010]
Variant 9-105558154-CT-C is Benign according to our data. Variant chr9-105558154-CT-C is described in ClinVar as [Benign]. Clinvar id is 162565.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00904 (1377/152256) while in subpopulation AFR AF= 0.0318 (1320/41530). AF 95% confidence interval is 0.0304. There are 21 homozygotes in gnomad4. There are 663 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
Review Status: criteria provided, single submitter
Collection Method: clinical testing
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
