Genes affected
INSL3 (HGNC:6086): (insulin like 3) This gene encodes a member of the insulin-like hormone superfamily. The encoded protein is mainly produced in gonadal tissues. Studies of the mouse counterpart suggest that this gene may be involved in the development of urogenital tract and female fertility. This protein may also act as a hormone to regulate growth and differentiation of gubernaculum, and thus mediating intra-abdominal testicular descent. Mutations in this gene may lead to cryptorchidism. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2012]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 18, 2022 | The c.380C>T (p.T127I) alteration is located in exon 2 (coding exon 2) of the INSL3 gene. This alteration results from a C to T substitution at nucleotide position 380, causing the threonine (T) at amino acid position 127 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
