Genes affected
GMCL1 (HGNC:23843): (germ cell-less 1, spermatogenesis associated) This gene encodes a nuclear envelope protein that appears to be involved in spermatogenesis, either directly or by influencing genes that play a more direct role in the process. This multi-exon locus is the homolog of the mouse and drosophila germ cell-less gene but the human genome also contains a single-exon locus on chromosome 5 that contains an open reading frame capable of encoding a highly-related protein.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.142G>A (p.G48S) alteration is located in exon 1 (coding exon 1) of the GMCL1 gene. This alteration results from a G to A substitution at nucleotide position 142, causing the glycine (G) at amino acid position 48 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
