The c.4736A>G (p.E1579G) alteration is located in exon 10 (coding exon 10) of the SPHKAP gene. This alteration results from a A to G substitution at nucleotide position 4736, causing the glutamic acid (E) at amino acid position 1579 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
