The c.202A>G (p.T68A) alteration is located in exon 3 (coding exon 3) of the HOMER1 gene. This alteration results from a A to G substitution at nucleotide position 202, causing the threonine (T) at amino acid position 68 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
