Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_001291415.2(KDM6A):c.1999C>G(p.Leu667Val) variant causes a missense change. The variant allele was found at a frequency of 0.00136 in 1,205,284 control chromosomes in the GnomAD database, including 13 homozygotes. There are 397 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L667F) has been classified as Uncertain significance.

Genes affected

KDM6A (HGNC:12637): (lysine demethylase 6A) This gene is located on the X chromosome and is the corresponding locus to a Y-linked gene which encodes a tetratricopeptide repeat (TPR) protein. The encoded protein of this gene contains a JmjC-domain and catalyzes the demethylation of tri/dimethylated histone H3. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Apr 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.012268305).

BP6

Variant X-45063737-C-G is Benign according to our data. Variant chrX-45063737-C-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 134596.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00658 (736/111922) while in subpopulation AFR AF = 0.0231 (711/30741). AF 95% confidence interval is 0.0217. There are 6 homozygotes in GnomAd4. There are 187 alleles in the male GnomAd4 subpopulation. Median coverage is 22. This position passed quality control check.

BS2

High AC in GnomAd4 at 736 XL,AD gene.
