Genes affected

SOHLH1 (HGNC:27845): (spermatogenesis and oogenesis specific basic helix-loop-helix 1) This gene encodes one of testis-specific transcription factors which are essential for spermatogenesis, oogenesis and folliculogenesis. This gene is located on chromosome 9. Mutations in this gene are associated with nonobstructive azoospermia. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2013]

The c.1078G>A (p.E360K) alteration is located in exon 8 (coding exon 8) of the SOHLH1 gene. This alteration results from a G to A substitution at nucleotide position 1078, causing the glutamic acid (E) at amino acid position 360 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
