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]

Ambry Genetics

Sep 20, 2023

The c.655T>C (p.Y219H) alteration is located in exon 4 (coding exon 3) of the SPATC1L gene. This alteration results from a T to C substitution at nucleotide position 655, causing the tyrosine (Y) at amino acid position 219 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
