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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.1804046).

The c.1108A>G (p.R370G) alteration is located in exon 3 (coding exon 2) of the TEX13A gene. This alteration results from a A to G substitution at nucleotide position 1108, causing the arginine (R) at amino acid position 370 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
