Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_001009613.4(SPANXN4):ā€‹c.92T>Cā€‹(p.Leu31Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000555 in 1,171,662 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 18 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 13/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L31M) has been classified as Uncertain significance.

Genes affected
SPANXN4 (HGNC:33177): (SPANX family member N4) This gene represents one of several duplicated family members that are located on the X chromosome. This gene family encodes proteins that play a role in spermiogenesis. These proteins represent a specific subgroup of cancer/testis-associated antigens, and they may be candidates for tumor vaccines. This family member belongs to a subgroup of related genes that are present in all primates and rats and mice, and thus, it represents one of the ancestral family members.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2024The c.92T>C (p.L31P) alteration is located in exon 2 (coding exon 2) of the SPANXN4 gene. This alteration results from a T to C substitution at nucleotide position 92, causing the leucine (L) at amino acid position 31 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
