The c.229T>G (p.S77A) alteration is located in exon 2 (coding exon 2) of the NAALADL2 gene. This alteration results from a T to G substitution at nucleotide position 229, causing the serine (S) at amino acid position 77 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
