Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_StrongBS1_SupportingBS2_Supporting

The NM_005543.4(INSL3):c.115G>A(p.Val39Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000762 in 1,548,336 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V39L) has been classified as Uncertain significance.

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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.048655957).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0000774 (108/1395986) while in subpopulation EAS AF= 0.00289 (103/35690). AF 95% confidence interval is 0.00243. There are 0 homozygotes in gnomad4_exome. There are 57 alleles in male gnomad4_exome subpopulation. Median coverage is 35. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 10 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Ambry Genetics

Oct 26, 2022

The c.115G>A (p.V39I) alteration is located in exon 1 (coding exon 1) of the INSL3 gene. This alteration results from a G to A substitution at nucleotide position 115, causing the valine (V) at amino acid position 39 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
