Genes affected

SOHLH2 (HGNC:26026): (spermatogenesis and oogenesis specific basic helix-loop-helix 2) This gene encodes one of testis-specific transcription factors which are essential for spermatogenesis, oogenesis and folliculogenesis. This gene is located on chromosome 13. The proteins encoded by this gene and another testis-specific transcription factor, SOHLH1, can form heterodimers, in addition to homodimers. There is a read-through locus (GeneID: 100526761) that shares sequence identity with this gene and the upstream CCDC169 (GeneID: 728591). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2013]

SOHLH2 links:

CCDC169-SOHLH2 (HGNC:38866): (CCDC169-SOHLH2 readthrough) This locus represents naturally occurring read-through transcription between the neighboring C13orf38 (chromosome 13 open reading frame 38) and SOHLH2 (spermatogenesis and oogenesis specific basic helix-loop-helix 2) genes. The read-through transcript encodes a fusion protein that shares sequence identity with the products of each individual gene. [provided by RefSeq, Nov 2010]

The c.841C>T (p.L281F) alteration is located in exon 11 (coding exon 10) of the CCDC169-SOHLH2 gene. This alteration results from a C to T substitution at nucleotide position 841, causing the leucine (L) at amino acid position 281 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
