Genes affected
TEX13A (HGNC:11735): (testis expressed 13A) This gene is similar to a mouse gene that is expressed in the testis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]
IL1RAPL2 (HGNC:5997): (interleukin 1 receptor accessory protein like 2) The protein encoded by this gene is a member of the interleukin 1 receptor family. This protein is similar to the interleukin 1 accessory proteins, and is most closely related to interleukin 1 receptor accessory protein-like 1 (IL1RAPL1). This gene and IL1RAPL1 are located at a region on chromosome X that is associated with X-linked non-syndromic cognitive disability. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.493G>T (p.A165S) alteration is located in exon 3 (coding exon 2) of the TEX13A gene. This alteration results from a G to T substitution at nucleotide position 493, causing the alanine (A) at amino acid position 165 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
