Genes affected

RIPPLY1 (HGNC:25117): (ripply transcriptional repressor 1) This gene encodes a protein similar to a zebrafish protein which acts as a transcriptional repressor in and is required for somite segmentation in zebrafish embryos (PMID: 16326386). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

CLDN2 (HGNC:2041): (claudin 2) This gene product belongs to the claudin protein family whose members have been identified as major integral membrane proteins localized exclusively at tight junctions. Claudins are expressed in an organ-specific manner and regulate tissue-specific physiologic properties of tight junctions. This protein is expressed in the intestine. Alternatively spliced transcript variants with different 5' untranslated region have been found for this gene.[provided by RefSeq, Jan 2010]

MORC4 (HGNC:23485): (MORC family CW-type zinc finger 4) In human, the four current members of the microrchidia (morc) gene family share an N-terminal ATPase-like ATP-binding region and a CW four-cysteine zinc-finger motif. The protein encoded by this gene also has a nuclear matrix binding domain and a two-stranded coiled-coil motif near its C-terminus. This gene is widely expressed at low levels in normal tissues and has elevated expression in placenta and testis. Alternative splicing results in multiple transcript variants encoding distinct proteins. [provided by RefSeq, Jan 2010]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.874
• BS2: High Hemizygotes in GnomAdExome4 at 7 AR gene
