Genes affected
SPATC1L (HGNC:1298): (spermatogenesis and centriole associated 1 like) Enables identical protein binding activity. Predicted to act upstream of or within several processes, including actin polymerization or depolymerization; positive regulation of cAMP-dependent protein kinase activity; and positive regulation of protein kinase A signaling. Predicted to be located in sperm connecting piece. Predicted to be active in centrosome. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.757C>T (p.R253C) alteration is located in exon 5 (coding exon 4) of the SPATC1L gene. This alteration results from a C to T substitution at nucleotide position 757, causing the arginine (R) at amino acid position 253 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
