Genes affected

LAGE3 (HGNC:26058): (L antigen family member 3) This gene belongs to the ESO/LAGE gene family, members of which are clustered together on chromosome Xq28, and have similar exon-intron structures. Unlike the other family members which are normally expressed only in testis and activated in a wide range of human tumors, this gene is ubiquitously expressed in somatic tissues. The latter, combined with the finding that it is highly conserved in mouse and rat, suggests that the encoded protein is functionally important. An intronless pseudogene with high sequence similarity to this gene is located on chromosome 9. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.968
• PP5: Variant X-154477966-A-G is Pathogenic according to our data. Variant chrX-154477966-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 444872.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chrX-154477966-A-G is described in Lovd as [Likely_pathogenic].
